What you need is a bunch of coordinating scraps, fabric fusion glue, a pair of shoes. scissors and a paint brush. It should be a cheap paint brush because you will probably have to throw it away afterwards. Now the blog I read mentioned thinning the glue with water to make it go farther, but I found that I had a hard time getting the fabric to stick when I did that so I used it at original strength. I also found that it worked best when I put glue on the shoe, on the back of the fabric and over the top of the fabric. That helped hold the fabric in place.
Basically you cut scraps to fit the edge of the shoes and glue away! It takes a little bit of time to get the fabric to lay where you want and to cut it to fit. My main problem with this project has been after the glue dried. The shoes are incredibly stiff. I have washed them but I think I will need to wash them again to help with that problem. Also next time I will use only two or three fabrics to make a more cohesive design.
