I was thrilled to see this challenge because I recently created a blog post about my Halloween decorations but didn't know how to share it with a larger number of crafters. I hope I'm forgiven for doing a double-post, as well as stretching the criteria a bit as this isn't simply art to hang on the wall, but rather the wall is the "canvas" for the art.
I thank Martha Stewart and some posts on Pinterest for the inspiration to create a colony of bats swarming down our staircase and out the window. This was very easy to do, a great project for all family members, or beginning crafters considering wall vinyl art.
I used Provo Craft vinyl purchased from Craft Warehouse, although there are other less expensive online vendors. I used 3 1/2 sheets of vinyl and transfer tape to create 49 bats ranging from 3"-17". October 31 cricut cart.
