Oh how brave! I admire your ability to go thru it all. The most I have been able to conquer is to go thru and get rid of prints that are "leftover" from making a quilt. If I fall in love with a precut and purchase extra yardage for whatever reason. Once the quilt is made, I am done with the print. I put it on the free table. I do keep all batiks and 30's. Afterall, I can't go too overboard.
