I found a BC Craft Fairs Calendar - How useful!
I recently discovered the existence of Hair Canvas, and I'm not sure if I want to try it. Hair Canvas is used to stiffen coats, and can be purchased reasonably at B Black & Sons, but even reasonable costs are a little on the high-side for my frugal crafting self. Fusible interfacing can be substituted if desired - it's easier to use, but doesn't have quite the same effect. If you prefer interfacing, there is a table of various interfacings and their uses here.
And I love this umbrella stand idea from craftycuban on Craftster. I would like to use this idea to make cache-pots for my plants. So colourful!
