I'm just starting out so I am about 50/50 keep vs. give away. I do have a hard time parting with them b/c I usually do something I know they will like, but I also have to like it, too! ha ha! I mostly do scrap quilts so I don't know how much each costs - a LOT of my fabric has come from the remnant bin. The one I am making for my dad will be close to a twin size and all the fabric was purchased for it - maybe $100 start to finish?? Thankfully our LQS sells their fabric for around $5/yd. I didn't realize how good I had it until I went to a couple other places! Whew! They do it as a hobby, not to make a fortune or anything. I do know they shop around to be able to offer us those prices...
