However, I love an easy craft & I have a great one for you!
You'll need:
shoebox tops
scrapbook paper, fabric, or wrapping paper
spray adhesive
tape
Spray the tops of the shoebox tops (doesn't that sound weird) with the spray adhesive. Lay it flat & press down to make sure it adheres.
Use tape to secure the paper to the sides of the tops.
Hang on your wall!
It'll take all of 15 minutes & look really cute. It's practically free. You can just go to your local shoe store & ask for tops to boxes & they'll give them to you. I found scrapbook paper for $.59 at a local craft store, but you might have some on hand. Fabric and wrapping paper are options as well. Also, you're helping the environment by using your "trash". :)
