I was browsing around the other day and came across Spoonflower, a company that lets users upload their own fabric patterns and prints them on organic cotton. Previous patterns are available for sale and there are some really, really beautiful and unique fabrics there.
It's pricey--ranging from $18 to $20 a yard, with 8x8" swatches going for $5 and fat quarters going for $11. Still, if you find something you really adore, a swatch or fat quarter is enough for a smallish project where it's a trim or a feature in a larger piece. Perhaps the center of a pillow or cushion, or the front panel on a purse or reusable shopping bag?
Even if it's not in your price range, go browse around for a few minutes just for the sheer enjoyment of the artistry in some of the patterns.
