If your blanket border should lie flat but waves or pulls inward, stop adding rounds and inspect where the distortion begins. Extra stitches crowded into an edge can create waves; an insufficient span of edging can draw the fabric inward. Check placement, gauge and corner instructions before deciding which change to try. A curled edge by itself does not prove a particular stitch-count error.
Separate the body from the border
Lay the blanket flat without stretching it. Did the body lie flat before the edging? Is the problem on one side, at the corners, or all around? If the body was already changing width, use the width diagnosis guide first. Adding more edging does not identify an earlier body error.
Check whether waves are part of the design. A deliberately ruffled or scalloped edge should not be judged against a straight-border shape. Keep the intended appearance beside your work: a narrow frame and a decorative frill have different goals.
Check the first attachment round
Designer Tonya at Nana’s Crafty Home explains, in her C2C border tutorial, how excess edging stitches can make waves and too few can bunch the fabric. She recommends laying the work down periodically to check it. Her stitch-placement counts apply to that construction; do not transfer them unchanged to every blanket.
On your own project, distinguish stitches worked into the tops of stitches from those worked along row ends. Follow the pattern’s distribution and mark short sections so you can compare them. If a correct-looking section and a distorted section differ in placement, note exactly where. Count any corners separately using the pattern’s convention.
Use a small comparison, not an arbitrary full-round change
For an original planning example, suppose a straight 20 cm trial edge lies flat with 28 evenly distributed border stitches in your chosen yarn and method. The same kind of 100 cm edge suggests 28 × 5 = 140 stitches as an initial comparison, excluding corners. Marking five 20 cm sections gives you checkpoints instead of discovering a surplus at the last corner.
This is a hypothetical measured trial, not a universal pickup ratio. It does not apply unchanged to different row heights, another stitch or a decorative repeat. If your border requires complete repeats, reconcile their count and any edge offsets with the pattern before working the whole side.
Check corners and gauge before reworking
If the straight sides look right but a corner does not, compare the corner sequence with the written pattern. A corner is not simply more of the straight edge. Avoid adding or removing stitches around every side to solve a problem confined to one turn.
Also check the yarn and hook you used. The Craft Yarn Council recommends comparing a gauge sample with the pattern. If you changed yarn or hook for the border, a small sample can help you assess that fabric before altering the whole blanket. Change one variable at a time so you can tell what helped.
Keep the finish you like, with a workable edge
Once you identify a misplaced sequence, one option is to undo back to the affected round and rework it, checking the blanket flat as you go. Do not assume washing or blocking will compensate for a substantial placement error; follow the yarn’s care instructions and test preparation on a sample.
You can keep your chosen color even if you reconsider border width or stitch. Try a short section beside the body to judge the frame it creates. After the construction is settled, update the separate border-yarn estimate and your project notes.
