If you had blocks she made those could easily be stitched onto squares to use in a quilt. Any afghans she made that were made out of blocks and then stitched together could be taken apart and done the same way. Just stitch it on like you see doilies done. I crochet and would rather know that my work was repurposed and loved rather than put in a box.
I am sorry for your loss and I hope you can find a way to enjoy the extra afghans.
