I thought about you a lot today and wondered how it is going! I think if you divide the blocks into piles according to size for the three (or four???) quilts, then square them up to one size -- taking off the least that you have to, and then putting them together in some way that will hold them. I thought your "whipping" was going to be like a basting stitch that probably wouldn't be removed. Then I would take my 4 x 7 big block and lay it down so I could see how wide the sashing needed to be to make it cover those edges. I hope this helps. No matter, remember they will be loved.
