I started like this too, buying everything in sight that appealed to me until I had a stash that was very large. I put the fabric in color categories and type-of-fabric categories, like floral, etc. in decorative boxes of the same color as the fabric. I does become a compulsion, for sure but now I look at what I have and realize I won't live long enough to do all I want, SO I have stopped buying except very small amounts from the quilt shop. It does no one any good if it's not used, so I am doing Linus blankets all the time and I vow to get a manageable stash and be much more balanced in the future. The cost is just getting too high to buy on a whim, at least for me.
