Rounded corner: Blanket Border & Corner Generator

A five-post corner fan trial

This border uses half double crochet along the sides and five half double crochets into each marked corner. It is a two-round study in making broader corner fans and retaining one central corner source. The goal is to compare this rounded-fan treatment with an ordinary three-stitch corner in a real sample. It does not certify that five posts will lie flat on every rectangular fabric; that depends on yarn, stitch height and the actual receiving edge.

Count the receiving rectangle

Prepare twelve ordinary bases on each long side and eight on each short side, plus four distinct corners. Forty side positions and four corner positions give forty-four bases. Mark the corners before attaching the edging. Use a smooth yarn compatible with the receiving fabric, an appropriate trial hook and a separate round-start marker. The start marker and corner markers perform different jobs after the first circuit, so do not rely on one marker for both.

Track a sixteen-stitch expansion

Work one half double crochet in each ordinary base and five in each corner base. A corner replaces one old position with five, increasing by four. Four corners therefore add sixteen stitches. The first round contains sixty half double crochets. Mark the third stitch of every five-stitch fan as the next corner. The other four stitches become ordinary positions for the following circuit; they are not four additional corner sources.

Work the second circuit without multiplying corners

Begin with the indicated uncounted two-chain height and join to the first actual half double crochet at the end. On the second round, work one half double crochet in each ordinary old stitch and five in each of the four marked middle stitches. Sixty old bases become seventy-six stitches. The second round begins at its round-start marker, which need not be a corner. Follow the old positions in order rather than moving the first increase to whichever stitch is nearest the join.

Evaluate the corner shape honestly

The two rounds contain 136 completed half double crochets altogether. This workload total is not the final perimeter, which is seventy-six stitches. Fasten off after the final join and weave ends without tightening the fans. Finish the sample as planned, then inspect whether the broader corner treatment ruffles or suits the receiving geometry. If a different increase is needed, choose or design a new counted construction. Do not remove posts while continuing to use the saved seventy-six-stitch result as a record of what was made.

FAQ and typical mistakes

Which stitch receives the next fan?

The third, middle stitch of the previous five-stitch group. Increasing into its first or last stitch moves the corner.

Does rounded mean a circular blanket?

No. This is a four-corner receiving rectangle with local fans. A circular border needs different source geometry.

Why is the sample rippling despite correct counts?

The chosen increase may not suit the physical edge. Preserve the accurate record and make a separate measured alternative rather than calling the original trial flat.

Exact generator inputs and full instructions

Use the rounded construction, long sides 12 ordinary bases, short sides 8 ordinary bases and 2 border rounds. Palette: #44758B, #44758B. The resulting main counts are 60, 76. In UK terminology US sc becomes dc, hdc becomes htr, dc becomes tr, tr becomes dtr and front/back-post dc becomes front/back-post tr. Ordinary joins and height chains stay outside the main counts.
