Two-color corners: Blanket Border & Corner Generator

Change yarn by complete circuits

This four-round single-crochet frame alternates teal and terracotta as complete joined rounds. It explores color changes at a stable round-start location while four independent corner markers move through the growing border. The colors do not divide individual corners into contrasting halves. Each three-stitch corner group uses the same working yarn as the rest of its round. That distinction prevents an attractive palette description from concealing an unspecified within-corner color rule.

Prepare the starting perimeter

Count eighteen ordinary bases along each long side and ten along each short side, with four additional corner bases. The sides supply fifty-six bases and the corners four, giving sixty. Use similarly weighted smooth yarns, a compatible hook and a start marker distinct from the four corners. Work a trial color transition before applying this plan to a blanket. The tool specifies color order and stitch sources, but it does not hide tails or measure carried yarn automatically.

Work four counted expansions

Round one uses teal: one single crochet in each ordinary old base and three in each corner. Sixty sources become sixty-eight stitches. Join to the first actual single crochet and mark the middle stitch of every corner group. Terracotta makes round two, which contains seventy-six stitches. Teal returns for round three at eighty-four stitches, and terracotta completes round four at ninety-two. Each circuit adds exactly eight through the four three-for-one corner increases.

Make the yarn change a separate action

At the designated round-start point, secure or transfer the new yarn using a consistent sampled method. Make the required uncounted chain-one height and work the new round's first stitch in its actual old source. Neither the yarn attachment nor the height chain adds a counted position. Decide whether cutting each color or carrying it locally at the join gives the cleaner reverse surface for the intended fabric. Keep that finishing decision with the saved project notes.

Count by yarn without inventing consumption

Teal supplies the sixty-eight- and eighty-four-stitch rounds, 152 visible stitches. Terracotta supplies seventy-six plus ninety-two, 168. Their combined workload is 320 single crochets, while the final perimeter is ninety-two. Those values describe visible stitch counts, not yarn meters. Joins, tails and any carried section need an actual usage sample. Fasten after the last join, weave ends in matching rounds and inspect the color transition and all four corners.

Useful questions and repairs

Why is one corner striped inside its fan?

The supplied rule changes color between complete rounds. A mid-fan change belongs to a different design; restore the intended yarn before continuing.

Can I add a third palette color?

This construction alternates only the first two slots. A third entered color is not silently added to the sequence.

Why is the new round one stitch too long?

Look for a stitch worked into the height chain or an extra attachment stitch at the join before changing the corner counts.

Exact generator inputs and full instructions

Use the two-color construction, long sides 18 ordinary bases, short sides 10 ordinary bases and 4 border rounds. Palette: #2B6470, #D58D5E. The resulting main counts are 68, 76, 84, 92. 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.
