I have several stamped-for-embroidery pillowcases that already have the holes along the edge for attaching crochet. I just never knew how to go about attaching it. Well, I sort of knew but, having never crocheted before and finding most instructions daunting, I've never even tried. But, there may be hope for me yet. Kathleen Mower, on her blog Miss Abigail's Hope Chest, has a tutorial for an easy zig-zag crocheted edging that might be the perfect thing to finish my project. Perhaps yours, too. She added hers to a towel (and it took just 30 minutes!), but it should work equally well for pillowcases. If you want to try this, she suggests skipping over some of the holes, choosing ones that are spaced about 3/8-inch apart; otherwise there won't be enough room for the little diamond shapes.
Stitch School, which used to be an occasional feature on my Primrose Design blog, now has its very own space on the web. You'll find the same tutorials, including step-by-step instructions and photographs, that you've come to love, and I'll be adding new stitches periodically. I'll also feature subjects related to hand embroidery.
