i think you enbelish befor quilting that would be a few to many layers to sew through im thinking. most off the old crazy quilts dident even have batting they used he foundation material as batting or you could put a layer off flannel in as batting you definityl dont whant anything high loft or heavy since the top will already be kind off heavy on its own i would probly use silk batting in a crazy quilt since its thin and light wheight. i think ther is a book called crazy quilts or somethung like that cant totally remember it good lots off ideas for stiches. hope that helps i have a gerbage bag full of ties planning to make a crazy quilt but havent gotten that far yet
