Pillow case crocheted edging - This one starts after the blanket stitch is already done so, if you can't figure that out, you'll have to find a tutorial (there are some on youtube). This technique could, certainly, be used on other items, purchased clothes, cut offs, jeans, capris, curtains, towels...pretty much anything.
Base stitch for crocheted edgings - also see stacks of pillowcases etc. on this site.
