There are “wave” blocks to go along with the turtle blocks in the quilt I”m working on. I’ve quilting these “waves” before when I made a snail’s trail quilt and I made the same initial mistakes as last time. I think, in future, I need to write the color names on the foundation paper. I can’t remember what method I used for the snail’s trail quilt but the centers came out nicer so I need to keep that in mind should I use this block pattern again. The wave blocks are slower going so they’ll take a little while to work through before I can piece the top of the quilt.
