I Learned to make this bag on Martha Stewart a while ago. Since then I have gotten better! Also I learned a few tricks to make it easier...so buy your canvas at a good fabric store, Joannes is fine. The stuff from Walmart is too flimsy. Next use 100% wool felt, it is costly but you only use a little bit and it is SO much easier to cut. It cuts very smoothly.
I have discovered that by using these supplies the bags are really quite "green". Besides the fact that they are all made from renewable resources... it is also better to use your own bag then the store ones! See how I think. This bag is for my sister. She makes a big effort to be green. I wanted to support that.
So Happy Birthday, Tanya!
