Got two different ones started.
One has a center square with a fabric that reminds me of what would be in a cornucopia. Wish I had more of that but it was in a box of scraps and was the only one.
The other blocks I'm doing combine fabric with colorful autumn leaves and with pumpkins.
I don't particularly do Halloween either, just fall.
First block I did with the leaves and pumpkins was way too busy and all you saw was a mess so I switched the orientation of the pieces and it made all the difference in the world. Was afraid it wouldn't work at all, but now I like it.
