I am a little late with this....(just call me "tail end Charlie"). I would leave them whole to wash them, then re-assess when they have dried out and you can examine them closely and more comfortably. I think it is a wonderful collection and even those that are a little to shredded for repair could have sections cut out and "re-purposed", I have seen some sweet cushions and bears made from old quilt pieces. Let us know how you get on.
