Sure, you could buy all the letters of the alphabet for a wall mural in one go from one source, but if you have time (and patience!) to collect them over time you'll get a more interesting, unique result like Kira did.
Looking for a more frugal alternative to an alphabet mural she'd seen in a Pottery Barn Kids catalog, Kira began collecting different letters whenever she found something she liked and that was a good deal. Hers mainly come from Goodwill, Wal-Mart and Etsy. She enlisted her kids' help painting them and she covered many with scrapbooking paper.
We like this much better than a cookie-cutter version of the alphabet and can imagine the thrill of the hunt as Kira crossed letters off her list over the course of a year. You can visit Kira at her blog, Sew. Craft. Create.
