I was looking through my paper stash, and couldn't find what I was looking for. The only answer was to dig into my fabric stash and head to the photocopier. Photocopied fabric is in many respects better for my project work as it is thinner than scrapbook papers (and therefore easier to draw on), cheaper, and allows a much wider variety of choice - from my rather plentiful fabric stash!
These cards were fun, and quite quick to make too. I'm off to experiment and make some more for my shops.
