Okay, here are my 4 sets. The blue caterpillar/mushroom block is 12-1/2" square. The "Eat Me" cupcake block is 6-1/2" square. The Queen of Hearts is 6-1/2" square. And the rose/paintbrush block is 9-1/2" wide by 6-1/2" tall. I probably won't make any more sets except for my personal use. I just wanted to get these done before the Boomerang swap starts. Thanks for letting me play.
