I am new to this, but I have a ton of scrapbooking supplies and have had the same issue with them. So with this hobby, so far, I am only buying fabrics if I have a specific project. Then I work on that.
This weekend, my BIL came over and had been garage saleing. He brought me entire box of fabrics. So I will play with that and see if I can make a crazy quilt for them with it.
But mostly, I just try to stay out of the stores if I can. Good luck!
