I bought these hooks at Hobby Lobby on the 60% off aisle! I didn't care for the graphics on them so I bought them with the intention of redoing them.
I removed the hooks and started the mod podge process using some scrapbook paper. Initially I wanted to do initials but the more I thought about it I liked the idea of having quotes up on pretty paper. I had in my craft stash a book of quotes on vellum. I cut out the quote and glued it. I wouldn't put modge podge over the vellum. I tried it on one and the vellum just bubbled. You may have better luck but my advice is don't modge podge over the vellum.
You can use Christmas paper for a more seasonal look.
