I made both my sons and my husband quilts using the card trick block.
I mixed the fabrics among the 3 quilts such that each one had at least one from the other two quilts. Sort of "connected" all of them. None of the three of them will let anyone else "snuggle" with Mom's quilt.
Now, I have to make one for my son's fiancee...will incorporate scraps from my son's quilt into hers. :-)
