Right at the moment, the Australian dollar is worth 91 cents US and 95 cents Canadian. So there's not a lot of difference. The Aussie's seem to be paying the most per metre. If you were shopping in Australia right now, you'd be paying on average between $15 and $28 US per metre. A metre is 39", a little longer than a yard...........but probably not an extra $10 worth!
I'm a big fan of reusing and scavenging. I've gotten some awesome 100% cotton fabric from good quality bedskirts at the secondhand store.
I also like trading fabric out of my stash. Get to see something new to me, and share a nice fabric with someone else, too.
What are you going to do if fabric prices go up? Got any good thrifty tips and suggestions?
