I just recently bought a sheet and pillow case set and it has those wonderful little holes (otherwise known as hemstitching along the hem just right for sticking a crochet hook through. I was tickled pink.I figure a size 20 thread and a #10 hook and this pattern (top edging),
from the Ultimate Pineapples for Your Home, should work out just fine. This hemstitching is not the normal along the edge so you have to treat it a little differently. after attaching the thread through the first 2 holes and making my first sc, I chained 1 and inserted hook into the same hole i came out of last st and next hole for the next sc.
