I have two ideas for the green outfit. Do you have any of the floral left? You could make a yo-yo to sew on the onesie but then they can't use it with other outfits so my second suggestion is, what if you added criss cross straps that button on the front?
Actually I had 2 strips about 2" x 8" left over. I tried making a yo-yo, but it turned out a no-no.
I've never made them before, and the circle was just too darn small to do anything with. Now I have one strip about 2" x 8" left over. Not enough to do much with. I would go and just buy another of the green fabric FQ, but it was totally in a bundle so I can't get it as a single. Ah well. Maybe I can find a nice coordinating ribbon or something to jazz it up.
