A crochet tunic sweater sits in that perfect in-between spot — longer than a jumper, easy over leggings, and forgiving enough that fit stress disappears. This free crochet tunic pattern keeps the stitch work simple so the length does the styling for you, which makes it a solid pick if you’ve never tackled a full garment before. Wear it slouchy through autumn or belted when you want more shape. Written instructions are yours to grab, no cost.
A boat neckline and elbow length sleeves make this mesh tunic one of those pieces that works just as well tucked into jeans as it does worn loose over leggings. The open mesh body keeps it light enough for warm weather while the tunic length gives it more coverage than a standard top. If you like airy pullover styles, this crochet long sleeve sweater takes the same open mesh concept into a full sleeve format.
Tunic Sweater Crochet
Lion Brand Comfy Cotton Blend gives the finished fabric a soft drape and a subtle color variation that makes the mesh pattern look more complex than it actually is. The construction uses flat front and back panels seamed at the shoulders and sides, with sleeves picked up and worked outward from the armhole. The whole build is beginner friendly because the mesh repeat is just one stitch pattern carried all the way through with no shaping until the sleeve join.
Materials and Tools
- Category 3 (light) yarn — the original uses Lion Brand Comfy Cotton Blend (approximately 392 yards per 7 oz cake). A smooth, light yarn is important here because the mesh relies on drape, and heavier yarn will make the garment stiff rather than flowy.
- A 7.0 mm crochet hook (deliberately oversized for the yarn weight, which is what creates the open, airy mesh)
- Tape measure
- Scissors
- Tapestry needle
- Multiple stitch markers
Core Stitch to Learn
Difficulty and Time
This is an advanced beginner to intermediate project. The stitch work itself is manageable once the repeat clicks, but a few techniques take focused attention: the stacked single crochet (a new move for many crocheters), the measurement math before you start, and the mattress stitch seaming. If you give yourself time to read through each step before you work it, nothing here is beyond reach.
Beginner Technique Notes
Here’s a close look at every technique in this pattern before you cast on:
- Working into the bottom bump of the chain: Most beginners work into the front loop of a chain stitch, but this pattern directs you into the bump on the underside. Flip your chain over and you’ll see a row of bumps running along the back — that’s where your hook goes. Working into the bumps creates a neater foundation edge.
- The stacked single crochet: This is the most unfamiliar technique in the pattern and it’s worth practicing on a small swatch first. Chain 1, then single crochet into the first stitch (that’s your bottom layer). Next, insert your hook under the left vertical “leg” of that single crochet you just made, pull up a loop, and complete a second single crochet on top of the first. Together these two stitches create a stable, double-height unit that matches the height of a double crochet — which is what keeps the edge tidy and your mesh rows even.
- The mesh repeat: The core repeat is chain 1, skip 1 stitch, then double crochet in the next 2 stitches. On every subsequent row, your chain-1 sits directly over the previous row’s chain space, and your 2 double crochets sit over the previous row’s 2 double crochets. Tip: if you lose your place, look at the row below — your chain-1 always goes over a chain-1 space, and your double crochets always sit on top of double crochets.
- The stitch multiple: This pattern is worked in multiples of 3 plus 2 stitches. When you chain your foundation, count your stitches after Row 1 and confirm the total fits that rule. Tip: write the number down so you can check it again if something looks off partway through.
- Positive ease: This means deliberately making the garment slightly wider than your actual bust measurement. Adding 2 inches of ease gives you comfortable room to move inside the tunic without it feeling snug or pulling across the chest.
- The mattress stitch seam: Unlike slip-stitch seaming, the mattress stitch is worked with a tapestry needle through the sides of the stitches, creating an almost invisible seam. You insert the needle under the “bar” between stitches on each piece, alternating from side to side in a ladder pattern, then gently pull the yarn to close. It sounds fiddly but the result is a beautiful, invisible join that lies completely flat.
- Two seaming stitches per crochet row: When attaching the sleeves to the body along the row-ends, you’ll place 2 mattress stitches for every single crochet row of the body. This compensates for the height difference between needle stitches and crochet rows and keeps the seam flat rather than puckered.
- Seaming from the armpit outward: For the side seams, starting at the armpit and sewing downward lets you try the tunic on before you finish and adjust the side slit height while you still can.
The Pattern
The tunic is made from two identical body panels and two sleeves, all sized to your own measurements. The panels and sleeves are sewn together using the mattress stitch.
Step 1: Take Your Measurements and Do the Math
Before you chain anything, gather these numbers:
- Panel width: Measure around the widest part of your bust. Add 2 inches of positive ease for a comfortable fit. Divide that total by 2 — that’s the width of each panel. (Example: 34 inch bust + 2 inch ease = 36 inches. Divided by 2 = 18 inch panels.)
- Tunic length: Measure from the top of your shoulder down to where you want the tunic to end.
- Armhole depth: Measure from your shoulder down to where you want the armhole to end.
- Sleeve width: Double your armhole depth. (Example: 7.5 inches × 2 = 15 inch sleeves.)
- Sleeve length: Measure from the center back of your neck down your arm to where you want the sleeve to end. Subtract one quarter of your total bust measurement from that number to find your exact crochet length.

Step 2: Front and Back Panels (Make 2)
The stitch pattern works in multiples of 3 plus 2 stitches.
- Foundation chain: Chain in multiples of 3 until the chain reaches your calculated panel width.
- Row 1 (base row): Half double crochet into the second chain from your hook, working into the bottom bump of the chain. Half double crochet across every chain. Confirm your final stitch count equals a multiple of 3 plus 2. Turn.
- Row 2 (mesh setup): Work a stacked single crochet in the very first stitch. Double crochet into the next stitch. Then repeat across: chain 1, skip 1 stitch, double crochet in the next 2 stitches. Your last two stitches will be double crochets. Turn.
- Row 3 (mesh pattern): Work a stacked single crochet in the first stitch, double crochet in the next double crochet. Then repeat across: chain 1 (sitting directly over the previous row’s chain space), double crochet in the next 2 double crochet stitches. Turn.
- Remaining rows: Repeat Row 3 until the panel reaches your desired tunic length.
- Final row: Turn, chain 1, and work 1 half double crochet into every double crochet stitch and 1 half double crochet into every chain-1 space all the way across. Fasten off.
Step 3: Sleeves (Make 2)
Sleeves follow almost the same method as the panels but do not get a final row of half double crochet.
- Foundation chain: Chain in multiples of 3 until the chain reaches your calculated sleeve width (approximately 14 to 15 inches, keeping in mind that the mesh will expand the piece slightly).
- Row 1: Half double crochet in the second chain from the hook and in each chain across. Turn.
- Row 2: Work a stacked single crochet in the first stitch, double crochet in the next, then chain 1, skip 1, double crochet in the next 2 stitches. Repeat across. Turn.
- Row 3: Repeat the mesh pattern from Row 3 of the panel instructions.
- Remaining rows: Repeat Row 3 until the sleeve reaches your calculated sleeve length. Fasten off on a normal pattern row (not after a modified final row).
Step 4: Assembly and Seaming
The Neckline and Shoulders
- Lay your front and back panels flat on top of each other, matching the top edges (the final half double crochet rows).
- Find the exact center stitch of your panel.
- Measure outward symmetrically from the center to map your desired neck opening and mark both sides with stitch markers.
- Using a tapestry needle and a strand of yarn three times the length of the shoulder seam, use the mattress stitch to sew from the outside edge of each shoulder inward toward your neck stitch markers. Secure and fasten off.
Attaching the Sleeves
- Lay the connected body panels flat. Find the exact center stitch along the long foundation edge of your sleeve.
- Pin that center sleeve stitch directly onto the shoulder seam.
- Pin the rest of the sleeve edge evenly down the sides of the front and back panels using stitch markers.
- Sew the sleeve to the body using the mattress stitch. When sewing into the sides of the body rows, place exactly 2 sewing stitches per crochet row to ensure the sleeve lays flat without puckering.
Side Seams and Slits
- Fold the garment so the sides and sleeves line up.
- Measure up from the bottom hem to determine how high you want your side slits to be and mark the point with a stitch marker.
- Pin the side seams together from the slit marker up to the armpit, and then continue pinning down the length of the sleeve to the cuff.
- Start sewing at the armpit and work downward to the top of the side slit — this lets you try it on and adjust the slit height before you fasten off.
- Sew from the armpit down the sleeve to the cuff.
- Weave in all loose yarn tails and your mesh tunic is ready to wear.
Tips and Troubleshooting
- Swatch for width, not gauge. Because the panels are sized to your measurements in inches rather than to a stitch-per-inch gauge, crochet a few rows in the mesh pattern and measure the actual width in your finished chain rather than counting stitches. Adjust your chain until the width hits your target.
- Practice the stacked single crochet on a swatch before the real panel. It’s the most unfamiliar motion in this pattern and worth five minutes of practice before you commit to Row 2 of your main panel.
- Sew from the armpit downward, not upward. This is the most useful assembly tip in the whole pattern — it lets you try the tunic on before finishing and adjust the side slit height without undoing completed seams.
- Check your stitch multiple after Row 1. The mesh only works cleanly if your stitch count is a multiple of 3 plus 2. Catch it here and fix it before the repeat begins.
- Use stitch markers generously. You need them for the neck width, the sleeve center, the slit height, and the side pinning. Have at least 6 to 8 handy before you start assembly.
Yarn Substitution
The yarn choice matters here in one specific way: you need a light (Category 3) yarn on a 7.0 mm hook, and that combination is deliberate. The oversized hook relative to the yarn weight is what opens up the mesh and gives the tunic its flowy, airy drape. Moving to a heavier yarn will make the fabric dense and stiff — the tunic will lose the breezy quality that makes it a summer piece. Any smooth Category 3 yarn (cotton, cotton blend, or bamboo) will work beautifully. Avoid textured or fuzzy yarns, which obscure the mesh openings.
Frequently Asked Questions
1. I’ve never made a garment before — is this a good first one? It’s a very reasonable first garment if you’re already comfortable with basic stitches and are willing to learn the mattress stitch seam and the stacked single crochet. The biggest advantage is that you size it to your own body from the start, so there’s no hoping a pattern size will fit you.
2. What is positive ease and why does it matter? Ease is the extra room built into a garment beyond your actual measurement. Adding 2 inches of ease to your bust measurement means the tunic will be 2 inches wider than your body — comfortable to wear and not pulling across the chest. Without ease, a garment that matches your body exactly tends to feel tight in real life.
3. What is the stacked single crochet and why is it used instead of a chain-2 to start rows? A chain-2 turning chain at the start of a row often leaves a visible gap and can slant the edge. The stacked single crochet creates a taller, stabler unit that mimics the height of a double crochet without the gap or slant — giving you a cleaner, tighter edge stitch.
4. How do I know if my mesh row is correct? On Row 3 and beyond, every chain-1 should sit directly over the chain-1 space from the row below, and every pair of double crochets should sit directly over the pair of double crochets from the row below. If the chains and posts are shifting around, count the repeat from the beginning of the row and find where the pattern broke.
5. What does “2 seaming stitches per crochet row” mean when attaching the sleeves? Crochet rows are taller than individual sewing stitches. To make the sleeve lie flat when sewn to the body, you need to put 2 mattress stitches into the body for every 1 crochet row rather than 1 for 1. Using a 1-to-1 ratio leaves the seam loose and puckered; the 2-to-1 ratio distributes the sleeve evenly.
