ancient - this site you can join for free and you can download lots of plastic canvas patterns.
This one has free patterns for a few different crafts and gives you directions on how to bead, crochet, and cross stitch/plastic canvas.
Hopefully there will be something there that you can start with. Should give you enough to start with. If you want to try something and you can't find a pattern just ask. I may have the pattern here. I think I have a few hundred different ones.
And thank you chico and L4H for the kind words. You gals would have done the same if you had a virtual warehouse of craft supplies sitting in your closet going to waste.
