I really starch all the fabric I am currently working on, cause I'm a clumsy cutter. I wash everything I quilt even the stuff for ragging, so after, it tends to loose it's stiffness, and I have to put it back. So mine isn't about the quality of the fabric cause I do it to everything, flannels, even the back of my chenille. Just so I can get better cuts. That's just me. I've had flannel pill badly, some stuff for my rag quilts looks crappy after it's washed once it's made, so I do it cause I want no suprises. I had very nice lqs fabric that did not look as nice after I ragged it with certain flannels, would not have put the stuff together if I knew the end results. My dogs have a few quilts cause I only washed them after I finished.
