Wild and Free
Graphic 45 is one of my favorite sources. Their collections are well-thought out and they have a great variety in each collections to take your crafting to a higher plain. The Midnight Masquerade Collection is perfect for Mardis Gras-themed projects, but would also do well in Steampunk or mixed media. I have found that the 8 x 8 inch papers are all you need to make card fronts, etc. Look at all of their collections and you'll find a favorite that you cannot live without.
