Pattern photos don’t match the instructions.
(Ought to have started the 2nd leg rep at rnd 5 to match the photos.)

I added one more CC stripe before starting the heel.
Not cutting my yarn, just knitting 2 extra stitches after finishing leg.
row 3 of heel flap: start with 2 slip stitches.
Rows 3 and 5 of heel turn are missing a stitch (need 12 stitches before the decrease.)
Again, didn’t cut my yarn after the heel. Did 1x1 colorwork across heel stitches and picking up first set of gusset stitches. New beginning of round at start of instep.
