This is block #3 (yes, I had a piece of that bee fabric and did not resist )
Here are blocks 1-3 together. They are 6 1/2" blocks and come from Tula Pink's book City Sampler 100 Modern Blocks. I am using my Tula Pink stash with a few solids mixed in. You can find more info on my first post here. They are small blocks and don't require much material but I highly suggest pressing the seams open to allow the blocks to lay flat.
