Jenniky, you are doing a fabulous job of showing us ideas. And wouldn't you know it, I have that book but forget I have it all the time. Silly me.
Here are a few of my 35 Sunbonnet Sue blocks. Ruby (my DGD) is a hot pink lovin' little girl so I am going to border each block with hot pinks prints. I am planning to use your method of planning the layout of the SS because I want them to flow colorwise and then pin their individually picked pink borders, so I also don't have like prints right next to each other. Your system that you showed will work so well for doing this. Not sure I wouldn't have come up with it on my own. Sew, thanks a million... at least!!
