Ooooooooh! Pretty peththefabric!!! Rail fence is a fun pattern to experiment with colors... I've only done this in strips but I haven't used scraps so I can see the challenge in doing this pattern in smaller pieces. 1/2 yard should do the trick with stripping.
Worked on SBS today.. 26 to go.... I am blasting through the background fabric for this project and had to pull more from stash (I had to steal WOW from a future project but I overbought so hopefully, I will still have enough)..
