Do you wish to sell or donate?
Or do you like the color combos enough to just say 'what the heck' and cut them into 2 1/2" strips and make a lot of 1600 quilts for charity or gifts or for church, etc. This is about where I am with some of my older stash.
My two quilting groups depend on gifts of fabric which they then use for the quilts we make for the various charities. I know either would feel blessed to have a gift made to them.
