I am not a scrap quilter, so I don't keep anything smaller than a half yard (and probably shouldn't keep those). I tend to buy a minimum of three yards of anything, and if I like the fabric a lot, I'll buy the whole bolt.
Anything smaller than an 1/2 yard goes into a big tub of scraps that I seldom look at.
I also have a lot of FQ's, but I've stopped buying them because I don't think I've ever used any. (And please, no pm's asking to me to sell/donate etc)
My rationale now is that they are BAIT!! A certain friend of mine here on the board, loves scrappy quilts. When she was here recently, I let her go through and take what she wanted. We shipped a 23 lb. box home to her. So the rest are BAIT to entice her to come back and play! LOL
