Rainbow stripes and popcorn stitches in the same project is a commitment every row is a new color, and every stitch adds a raised three-dimensional cluster that makes the fabric thick, textured, and unmistakably handmade. This boxy crop top leans fully into that combination, with horizontal color bands worked in popcorn stitch rows from the hem up to the round neckline and through the short puff sleeves. For a different take on a textured, color-forward top, the crochet beach wear for ladies rainbow mesh skirt uses self-striping yarn to get the rainbow effect without the color-change management.
Summer Crochet Blouse
The construction uses a separate ball of yarn for each stripe color having all the colors wound and ready before starting makes the process smoother, since the changes come quickly. Each popcorn cluster is worked by completing several full double crochet stitches into the same stitch before joining them at the top, which gives the raised rounded shape. The boxy silhouette and short sleeves come together through simple rectangular shaping rather than complex curves. For another crop top with bold texture and a similar boxy fit, the crochet boho top with evil eye granny sweater handles a different motif-based texture in a comparable silhouette.

Front Piece & Neckline

Shoulders:
- Join yarn at the right edge. Work the Popcorn/SC pattern across only to the first marker. Turn and work back and forth on this section until you reach Row 45. Fasten off.
- Skip the center 10″ (the neck opening). Join yarn at the second marker and work the pattern across to the left edge. Repeat until Row 45.
Assembly
Alignment: Lay the Front and Back pieces together with Right Sides facing each other.
Shoulders: Using your hook, SC the shoulder seams together.
Sides: Measure 9″ down from the shoulder for the armholes and place markers. SC the side seams starting from the bottom hem up to the marker.
Finishing & Sleeves

- Join yarn at the neck. Work one round of SC evenly around.
- Round 2: *1 DC, DC2tog; repeat from * around.
- Rounds 3-7: Work 5 rounds of alternating FPDC and BPDC (Ribbing).
Sleeves: Attach yarn at the underarm of the armhole. Work the Popcorn/SC pattern in joined rounds until you reach your desired sleeve length.
Hem: Leave the bottom edge as-is for a modern, clean finish.
Technique Explainers & Pro-Tips
The Popcorn Stitch (PC): Work 5 DC into the same stitch. Drop the loop from your hook. Insert your hook from front to back through the top of the first DC made. Grab the dropped loop and pull it through.
Pro-Tip: Managing Color Changes: Since you are changing colors every two rows, carry your yarn up the sides of the panel rather than cutting it every time. This will save you from weaving in dozens of ends later!
DC2tog (Double Crochet 2 Together): This is a decreasing stitch used in the neckline. (Yarn over, insert hook, pull up a loop, YO, pull through 2 loops) twice. YO and pull through all 3 loops on the hook.
Blocking Guide
To give your blouse a professional drape, Steam Blocking is highly recommended for cotton:
Pin your finished garment to blocking mats, ensuring the edges are straight and the neckline is symmetrical.
Hold a garment steamer or steam iron 1-2 inches above the fabric.
Let the steam penetrate the fibers without touching the iron to the yarn (which can “kill” the cotton or flatten the popcorn stitches).
Allow it to dry completely before wearing. This will relax the stitches and ensure the 15″ length stays true.
