I've been doing this, too. My first attempts at binding were less than successful so until I get more comfortable at that it's pillowcases for me! The largest has been a large twin (bedspread size rather than quilt/dust ruffle) but did a combination of tying and machine quilting on that one. I pin, pin, pin the dickens out of them before I machine quilt. I also do the borders - starting with a seam 1/4 inch from the edge - before the center of the quilt. Any little puckers then end up in less noticeable areas. I don't want to do them this way forever, but for now - this gets them DONE!
