I always try to make a secondary swirly design.
I get the ones that are my favorite and put them on my wall in a wavy pattern and then design from there by adding the blocks that I think match on either side.
Also, usually when you cut poorly on a set, you usually have 3 that are not too bad. I use these to square my quilt so that I have some "extras."
Btw this is nice fabric for a OBW.
My only other hint is to tell you to play with it and when it is right, you will know it.
I hope this makes sense to you.
Good luck.
