Hi Profannie. Not sure about Canada, but in my area we have what are called "The Bins". It's part of Goodwill, but unlike the Goodwill stores The Bins sell close by the pound. I have gotten fabric items from them for a number of years (you get a lot for your money). The other places that are good, going to estate sales and garage sales too. You might find that it takes you a few trips, but you can get a lot. Most garage and estate sales have 50% off on the last day (because they want to get rid of stuff), you might also offer one price on a lot of shirts at one of these sales too. Good luck
