Thanks everyone for your help. I wanted to make something that did not require cutting a lot of other pieces, so the Arkansas Crossroads appealed to me in that I would not need to cut a lot of other size pieces. But thanks to you, I think the split nine patch may only need a couple of "plain" squares to complete. Since I have so many of those triangles, I will make a "practice block" of each pattern to see what works best. Will let you know the outcome.
IowaStitcher, we can't be the only ones with bags of those little triangles! It was a world wide swap. I did make one quilt using them but barely dented the collection I had.
