As I'm still in my thrifty stage of life I love free stuff, especially things that are edible or pretty or both. Here are some free textures.
Urban Outfitters gives 5 free songs every Monday on their blog, and has multiple 20 song LSTN cds for you to download, for free.
And my favorite, a guide to free food during SXSW in Austin, TX which starts this Friday. P.S. This illustration at the bottom of their webpage by Catherine Oshiro is adorable and very clearly is enhanced by the texture overlay.
