You might be able to put some small one together by stitching them together by hand with yarn, that is if there are any that would look together. But I agree with everyone else, don't cut them. I've crocheted for over 30 years and thankfully I and now in the process of crocheting, sewing and quilting for a grand-baby that is on the way. One suggestion that I could make is that you could get in contact with a Linus group; I'm sure that they would be happy to receive any that you would lake to give away. But please keep some in remembrance of your Mother.
