I'm sure there are Block-a-Palooza participants grateful for Heather's easy, simple Block 7, but it was too easy and simple to interest me. So I used it as the basis to design my own block.
1) removed the center 4-patch:
rules and voila, a new 'palooza block that's all me. Or as much "all me" as any grid-based block design can be. There are a zillion and one variations on this kind of block, and they've all be done by someone, somewhen. Shouldn't stop you from playing around on your own, though, because it's fun.
If you'd like specific instructions on how to make this block for yourself, let me know in the comments, and I'll share my constructions notes and some pics in a new post.

UPDATE: Instructions for this block are now available here.
