Wow! I feel ya'. I received my mil's stash and ufo's at her passing. I have 5-6 of them I have been looking at off and on for 5 years trying to figure out what she meant for them to be. I actually just got one top done for a large king size bed. I just finally came up with my own plan that used all the pieces (almost) that she had.
now to figure out how to sandwich and quilt the bugger
