Step One: Gather supplies. You'll need: Leather scrap or other thick material scrap, thrifted/old/not-cute fanny pack, tacky glue, and scissors.
Step Two: Cut out heart or other cute shape from your scrap material.
Step Three: Spread glue on the fanny pack where you'll be placing the shape, and also on the back of the shape.
Step Five: Let the glue dry for at least 30 minutes. You're done!
I also DIYed a simple money belt fanny pack I got for cheap at Joann's. You see that on Thursday, 'cause I definitely instagrammed my newly DIYed fanny packs together!
