I changed the way the all-rings row was anchored to the last row of mignonnette. I chose not to anchor ANY rings into the ring on the row before, but joined 3 rings to each thread space without attaching ANY of them to each other (to lie more smoothly if the hair wasn't perfectly smooth, which is usually isn't).

I added a picot to make 5 picots in a row instead of 4 on the larger ring. Added another beaded mignonette row, then another 2 rows the addition of which and the addition of more rows will accommodate varying lengths of hair.
