I consulted with a friend who said this block is called Block Party. I did a search and found some instructions on a guild community service site. The instructions are in PDF, which is handy. I wasn’t able to find anywhere else to confirm the name.
I added another few blocks to my total during the week and am now up to 15 blocks. My first plan is for 36, which means 21 more to go.
I cut up a few more fabrics so there are some new ones included. Since I am working without a design wall, mostly, I don’t know if I am duplicating layouts. I don’t think it likely, but I also don’t think it will matter if I am.
