Honestly, never started out with the intentions of having a stash. Years go by and sales go on and the totes multiply. So you start tucking away nice creamy background fabric, and how about some more blues-can never go wrong with that color. Then you pick up a yard of fabric for a future baby quilt; never mind conception hasn't even happened yet.
I did a full inventory this past fall and actually scared myself with the amount of fabric I have. I 'll never live long enough to make a decent dent. Obviously, I wasn't "scared straight", have purchased at least 25 yards since then. Did I mention that between hubby and BFF, I was gifted 44 fat 1/4s at Christmas.
So you are not alone and best not to fight it.
