Prewash for dyes that might run.
A quilted quilt is going to pull up a bit after washing.
Charms and other precuts I do not wash before quilting.
So far have not had any problems after washing a quilt when finished.
I put my batting in the dryer for a few minutes to get the fold lines out but do not wash it.
I don't know if thread shrinks or not. I use Coats and Clarks and Connecting Threads mostly.
I don't mind the slight shrinkage that occurs after washing. Looks fine to me.
I have combined pre cuts (not washed) and yardage that is prewashed. Cant see any difference after quilt is washed. I use 80/20 batting and I think that is what shrinks a little.
