Here’s my latest disappearing block. I found it in this YouTube: https://www.youtube.com/watch?v=BFyLNGMEHrg.
First, I cut it into nine equal parts. Since it was 12.75″ each cut was 4.25″ wide.
Then I rearranged the pieces and sewed it back together.
I really like this one. It seems like the possibilities for these block variations are infinite. Every time I think I’ve seen them all, another one appears.
