I don't like the sandwiching part of doing a quilt either and that's because I suck at it. Why don't you just tie your quilts like our grandmas used to do? It's your quilt so quilt it any way you like. It sounds like you need some distractions in your life. You should just go ahead and make some more quilt tops. Somehow you'll find a way to finish the others. Sorry about your darling husband. Cancer really sucks!
