I've seen hoop art all over the place but I don't know the first thing about embroidery but some cute fabric in the hoop could totally work because it's like pinning them to a shirt. So I made it, tried it and love it!
This is a 12 inch hoop. I just put my fabric in it then hot glued it onto the back inside part so the fabric wouldn't move around. Then we started adding the pins. We have more I just need to find what I did with them! :)
