How to Crochet a Coastal-Inspired Pullover Sweater

Materials & tools you'll need

Step 1 — Set up your foundation chain

Measure your body circumference and divide it by two to determine your chain length — aim for each pattern piece to be between 28 and 30 inches wide. Create a foundation chain with an odd number of stitches to this length. At the end of the chain, double crochet into the fourth chain from the hook, then continue double crocheting across the row to complete your foundation row.

Step 2 — Crochet the ribbed cuff

Work a front-post/back-post rib stitch by alternating one front post double crochet with one back post double crochet across the row, repeating this pattern for every row. Continue until the rib measures approximately 2 to 2.25 inches, finishing on the backside of the fabric. This same ribbed technique will be used for both the sleeve cuffs and the neckline.

Step 3 — Shape the body piece

Measure your body and add a few extra inches for ease, aiming for each body piece to be about 26 inches across. After the rib stitch, work in a rectangle shape up to the armpit, then continue upward toward the neckline, finishing the front piece with a scoop neck. Keep your stitch count even across rows so the front and back panels match.

Step 4 — Continue to length and switch colours cleanly

Keep crocheting until you reach your desired sweater length. When switching yarn colours for the coastal colour-block effect, always change colour on the same side for both the front and back pieces — this keeps the colour transitions lined up and creates a clean, uninterrupted line across the fabric.

Step 5 — Weave in ends and seam the pieces

Weave in yarn ends as you go rather than leaving them all until the end — this makes the final finishing much faster. Once the front piece, back piece, and both sleeves are complete, sew them together, matching up the ribbed cuffs and hem so the ribbing sits evenly around the whole sweater.

Step 6 — Block and wash the finished sweater

Block the sweater so it lies flat and fits properly before wearing or gifting it. When it needs cleaning, hand wash or machine wash on a gentle cycle using cool water and mild detergent, then lay it flat to dry rather than hanging it, to help the sweater keep its shape over time.
