Cornflower Sweater Crochet Pattern — Floral Granny Square Oversized Jumper

A cropped, oversized sweater built entirely from one flower motif square — no shaping, no decreases, nothing to grade. Make twenty squares, block them, sew them into two panels, and you have a jumper.

The Cornflower Sweater is a 9-page PDF written in US crochet terms. Every square starts from a six-chain ring and grows outward into a twelve-petal cornflower: round 2 sets twelve triple crochets with chain spaces between them, round 3 works each petal as a cluster of triple crochets drawn together through a single loop, and rounds 4 and 5 throw chain arches over the top to carry the motif out to its corners. Round 6 squares it off with solid triple crochet along each side and a chain-3 at each corner. The petal cluster is walked through yarn-over by yarn-over the first time it appears, so you are not expected to arrive already knowing it.

How much to make

The pattern is written to be oversized rather than sized, so you choose your own dimensions. The assembly diagram lays the sample out as seven squares across the arm span and three below for the body — ten squares per panel, around twenty for the whole sweater. At roughly 8 inches (20 cm) per blocked square that gives an arm span near 56 inches and a chest around 48 inches, worn cropped. Want more room through the arms, a longer body, or a closer fit? Add or drop a square. Nothing has to be recalculated, which is the point of building a garment this way.

Assembly

Squares are joined wrong sides together with a running stitch worked back and forth through the edge stitches, which leaves a double braided ridge on the right side — the seam becomes part of the design rather than something to hide. Front and back panels are made identically, then sewn along the shoulders and sides.

Blocking is not optional here. The pattern says so plainly: the squares need to be blocked to even out before they will sit square against each other. It is the difference between a sweater that drapes and one that puckers.

What you need

• Weight 4 (worsted / aran) yarn — the sample is a cotton/nylon blend
• 5 mm – 6 mm crochet hook
• Yarn needle for sewing the squares together
• Blocking materials
• Stitch markers as needed

Yarn quantity is not specified, as it depends entirely on how many squares you decide to make. Roughly twenty 8-inch squares in worsted cotton is a useful planning figure.

Skills used

Chain, slip stitch, triple crochet, clusters worked together, skipping stitches, chain arches, and a running-stitch seam. If you can work a granny square and sew a straight seam, you can work this.
