Paper Studio has a stack named Mirabelle that I fell in love with at first sight. The papers in it look like fabric and the prints they used really give a card front texture. Besides, I like the colors!
These are what I'll call "cheater" cards. The first one is from a sheet that had two large designs in the corners of the 12 x 12 sheet. I think they work pretty well for a card front.
The second one has sort of a toile looking paper on it. Easy peasy to make but they turned out pretty.
