I bet my stash is 3 - 4 ft high or better. When buying my fabric I try to buy a bit more...if it calls for 1/2 a yd then I will buy a full yd. And of course I try to buy everything on sale, but most of my stash has been bought at a couple of our local thrift stores. You have to go on a fairly regular basis to find it, but I can get anywhere from a couple of yds to 3, maybe 4 yds for $3 or $4.
