When you are cutting your blocks you have to be consistent, same color on the bottom every time, diagonal in the same direction each time. If you look at the picture below, I have the green on the right side of the blocks with pink, and on the left side of the block with purple. All of purple ones are the same so I will have no problem with them and all of the pink ones are the same. It is just the 2 groups that are opposites.
Some layouts will work, the one above doesn't because the green switches positions. The zig zag is OK and the one below is interesting. Now I think my playtime is finished with them and I have to make a decision. You know what that means. They will go in a box while I contemplate. The next classes are on the 17th and 24th so I will be playing with them again then. They may make 2 different quilts, grape, and watermelon.
