Ok, I've been sewing the red & white pairs to blue & white pairs to make 4 patches. Each square is 2.5". Unfinished 4's are 4.5" I have no real plan yet, but so far I've been stacking 4 sets of 4 patches together & I'm making sure to always sew a 4 patch with the red square in the upper right. I have vague plans to put 4 of these sets together, rotating them so a consistent pattern shows up. I havent had real time to work on a setup for them since K & I are sewing on all the UFOs. It's just nice to know I'm getting some bonus blocks when they fit in with my current projects.
