This Free crochet jumper pattern in granny squares, sized small and written so the square count stays manageable. Each motif works up in rounds on its own, which means the whole sweater is portable until the very last step. Lay the squares out, join them into panels, then seam the sides and underarms and the jumper is finished.
Starting from a single center ring and growing outward round by round, this sweater is built entirely from one giant granny square per panel — a construction method that feels almost meditative once the rhythm sets in. The orange and yellow color combination gives it a retro warmth, and the brown ribbed hem and cuffs anchor the palette without pulling attention away from the square itself. If you want to explore more granny construction in a different format, this granny square cardigan uses individual joined squares for a patchwork effect.
Crochet Granny Square Jumper
The front and back panels are each worked as a single oversized square grown to the correct dimensions before being seamed at the shoulders and sides. Sleeves are picked up from the armhole and worked outward, with the ribbed cuffs and hem added last as a finishing border. The result is a cropped pullover with real visual impact that comes from the geometry of the stitch rather than any complex shaping.
Why I love this one: the color-block granny rows let you experiment with any two-color combination and get a totally different result — same construction, endlessly variable personality.

Must-Know Stitch
Difficulty and Time
This is an intermediate project. Granny squares are a familiar technique, but building them to 18 rows and understanding the sleeve construction (ribbing, then increases, then straight rows) takes a level of planning and patience that beginner makers find easier on their second or third garment. The assembly — particularly centering the sleeve and matching the color-change seams — is where attention pays off the most.
The Pattern
Two giant granny square panels form the front and back. Two sleeves are worked flat from ribbed cuffs outward. Everything is assembled with slip stitch seams.
Front and Back Panels (Make 2)
Work 18 rows total. Each panel should measure roughly 18 inches when complete.
Using Color A and the 5.5 mm hook:
Row 1 — Start the center ring
- Make a slip knot and chain 3. Insert your hook into the first chain and make a slip stitch to form a ring.
- Chain 3 (counts as the first double crochet). Work 2 double crochets into the center ring (first cluster of 3 double crochets complete). Chain 2 (first corner space).
- Work 3 double crochets, chain 2 into the ring three more times. You will have 4 clusters separated by 4 chain-2 corner spaces.
- Slip stitch into the top of the initial chain-3 to close. Chain 1, cut yarn, and fasten off.
Row 2 — Change to Color B
- Attach Color B to any chain-2 corner space.
- Chain 3, then work 2 double crochets, chain 2, and 3 double crochets all into that same corner space.
- Move to the next corner space without chaining between. Work 3 double crochets, chain 2, 3 double crochets. Repeat in the remaining two corners.
- Slip stitch into the top of the starting chain-3. Do not cut yarn; continue with this color into Row 3.

Row 3 — Side spaces and corners
- Chain 3 and work 2 double crochets directly into the space beneath where you stopped.
- When you reach a corner space (chain-2), always work the full corner: 3 double crochets, chain 2, 3 double crochets.
- When you reach a side space, work a single cluster of 3 double crochets.
- Continue around without chaining between clusters. Slip stitch to close, chain 1, and cut yarn.
Rows 4–18 — Grow the square
- Continue the established granny pattern: 3 double crochets in every side space, and 3 double crochets, chain 2, 3 double crochets in every corner space.
- From Row 9 onwards, switch to 3-row color blocks.
- Complete 18 rows total. Set aside and repeat to make the second panel.
2. The Sleeves (Make 2)
Ribbing cuffs — switch to the 4.5 mm hook
- Make a slip knot and chain 10.
- Row 1: Work 1 single crochet into each chain across. (9 single crochets.) Chain 1 and turn.
- Row 2: Work front post single crochets across the row. For the very final stitch, work a regular single crochet. Chain 1 and turn.
- Repeat Row 2 until the band comfortably wraps around your wrist. (The creator made 44 rows, approximately 8.5 to 9 inches.) Chain 1, cut yarn, and fasten off.
Base sleeve row — switch back to the 5.5 mm hook
- Attach your main yarn to the first stitch along the long side edge of the ribbing cuff.
- Chain 2, then work 1 double crochet into every single row-end or hole along the edge. Chain 2 and turn.
Sleeve Rows 2–8 — gradual widening
- Row 2: Work 2 double crochets into the very first stitch space (counts as 3 double crochets with the chain-2). Skip 2 stitches, then work a 3-double-crochet cluster into the 3rd stitch. Repeat skip 2, cluster across. At the final space between the last stitches, work an increase of 3 double crochets. Chain 2 and turn.
- Rows 3–8: Continue working granny stitch clusters into the spaces. At the beginning and end of every row, place an increase cluster of 3 double crochets into the edge spaces to gradually widen the sleeve.
Sleeve Rows 9–41 — straight working, no more increases
- Work straight granny stitch rows without expanding. Do not add increases at the edges. Instead, work 2 double crochets in the first large opening and 1 double crochet in the final edge space.
- Alternate colors every 14 rows.
- Work until the sleeve reaches 41 rows total (approximately 18.5 inches long and 17 inches wide at the top). Fasten off.
3. Assembly and Borders
Shoulder seams and neckline
- Lay the front and back panels flat on top of each other.
- Count 5 clusters inward from the left corner and place a stitch marker; repeat from the right corner. Leave the middle open for the neck.
- Attach yarn at the outer edges and slip stitch the front and back panels together across those 5 clusters on both sides.
Bottom waistband ribbing — switch to the 4.5 mm hook
- Create a separate ribbing strip exactly like the cuffs: chain 10, work 1 row of single crochet, followed by rows of front post single crochet until the strip reaches 87 rows (approximately 18 inches long).
- Align it along the bottom edge of a body panel. Slip stitch the ribbing to the panel. To prevent stretching, work 2 slip stitches then skip 1 hole on the ribbing side only, repeating this rhythm across. Repeat for the other panel.
Attach the sleeves
- Lay the connected body panels flat. Fold a sleeve in half lengthwise to find its exact center point.
- Align the center of the sleeve with the shoulder seam and secure it with a marker.
- Slip stitch the sleeve edge completely down to the front and back body panels.
Side and underarm seams
- Fold the sweater inside out.
- Starting at the wrist cuff, slip stitch the underarm edges together, working down the sleeve, through the armpit, and down the side panels to the bottom waistband.
- To keep seams hidden, switch your yarn color to match the color stripe you’re currently seaming through.
Finish
- Tie off, cut the excess, and weave in all loose ends inside the sweater with a tapestry needle. Turn right-side out.
Tips and Troubleshooting
- Count your clusters before seaming the shoulders. The 5-cluster shoulder seam needs to be identical on both sides — uneven counting here makes the neckline sit off-center. Mark both sides before picking up your yarn.
- Increase smoothly across Rows 2 to 8 on the sleeves. The edge increases need to be consistent at both the beginning and end of every row through Row 8. Uneven edge increases produce a sleeve that’s wider on one side than the other.
- Match color-change yarn when seaming. Switching to the appropriate color while slip stitching through each color-block section is what makes the seams genuinely invisible from the right side.
- Use 2-then-skip-1 rhythm on the waistband attachment. This counteracts the natural stretch of the granny panel edge — without the skip, the waistband bunches; with too many skips, it pulls in.
Yarn Substitution
Any yarn that works comfortably on the 5.5 mm and 4.5 mm hooks will suit this pattern. The original uses two colors, and if you substitute, keeping both yarns from the same fiber family (both wool, or both acrylic) ensures they behave the same way at the seams and ribbing. The waistband and cuff ribbing need a yarn with some elasticity — avoid a stiff 100% cotton if you want the ribbing to grip. A wool or acrylic blend works well. The granny body can accept almost any smooth medium-weight yarn.
Customization Ideas
- Resize. The pattern is written for a size small, but adjusting the number of granny rows on the panels and the number of rows on the sleeves scales it to other sizes — measure a sweater you love and compare it to the 18-inch panel measurement.
- More colors. The two-color scheme is a starting point — work each row in a different color for a full rainbow granny, or use a single color for a classic look.
- Adjust sleeve length. More or fewer straight rows in the Row 9 to 41 section lengthens or shortens the sleeve without affecting the shaping.
- Change the neckline width. Seaming fewer than 5 clusters per shoulder gives a wider, more relaxed neckline; more clusters narrows it.
Frequently Asked Questions
1. Why are the panels giant granny squares rather than flat granny-stitch rectangles? Working in the round from a center ring is the traditional granny square method, and doing it at a large scale means the sweater body has natural diagonal fabric interest from the way rounds grow outward. The corner structure also creates a predictable seam at the shoulders that aligns more easily than panel edges.
2. My granny square doesn’t lie flat — it cups or ruffles. How do I fix it? Cupping means too few stitches at the corners (not enough increase); ruffling means too many. In a standard granny, corners always get 3 double crochets, chain 2, 3 double crochets, and sides always get a single 3-double-crochet cluster per space. If it still cups or ruffles, the issue is tension — try going up or down half a hook size.
3. Can I substitute the front post single crochet ribbing with a different ribbing method? Yes. Back-loop-only single crochet ribbing made as a separate strip (as used in many other patterns) works as a direct substitute — it just gives a slightly softer, less defined rib. The strip attachment method (slip stitching it on with 2-then-skip-1 rhythm) stays the same regardless of the ribbing stitch.
4. Why does the sleeve have a separate increase section before the straight rows? Sleeves need to be narrow at the wrist and wider at the shoulder. The increase section in Rows 2 to 8 builds that taper gradually by adding edge clusters each row, and then Rows 9 to 41 lock in the full width and work straight to the top. If you skipped the increases, the sleeve would be the same width as the ribbing cuff from top to bottom.
