I found that I had done the same thing, so everytime I attempted to just shop my stash, I still had to go to the LQS for blender fabrics.
In the last few months I have purchased some blender fabrics that have made it easier to find everything I need in my stash.
I particularly like Robert Kaufman's Fusion fabrics. Here is a link...scroll down the page to see the many colors.
