I can't claim to be extremely frugal, but I do wait for sales, hit the garage sales and other secondhand places to accumulate fabric and sewing "stuff". I love a bargain. I compare my bargain hunting to a man's game hunting. Both of us must have the tools to do the job, then we have to go (several times & places) where the game are (woods, fabric stores) to determine what is there, plan for the kill or project. Must be patient, know what to look for, then know what to do with it when you get it. It's a sport and for me, it is more fun when I bag the bargain.
This has been a fun and interesing thread. Thanks for getting it started.
