Gram E, I only know what I do and that is make 37 or 38 sets of 50 that are all the same or nearly all the same. I would not recommend trying to meet individual preferences it is too complicated. Oh, if I know someone "LOVES" pink, I might stick an extra square or two of pink in the set. This swap is meant to be fun, simple and for me to whittle down my stash. Yeah, I know I get back as many as I sent but.... I don't have to cut them and it is just so much fun looking at all 1800 or so little birthday surprises. I will dig out some photos of quilts I have made over the past few years with my little candies. I'll post them another time.
