After much admiring, I normally fold mine and store in my stash cupboard but I recently decided on a different approach. I like to pre-wash my fabrics to avoid shrinkage problems once the quilt is complete and I sometimes get confused over which fabrics have been washed and which haven't. So my new plan of action is to pre-wash all my fabrics before folding and storing. I don't do any triming because when I use my fabrics, I trim anyway to square them off and having to repeat this process (due to storage creases, etc) would only waste fabric. P.S. I do remove the threads that result from washing though.
