Looking at my stash, most of my fabrics started out as at least 1 - 3 yard cuts, unless they were originally remnants. The only precuts I have purchased have been batik jelly rolls and a couple of interesting fat quarter bundles from the sale bin.
I'm finding that the fabrics I most often need more of are the fabrics that will work well for backgrounds or for sashings or borders. I have lots of medium to dark value fabrics, lots of focus fabrics, but not as many lights or blenders, especially in the colors I use most often. So now I know what I need to keep in mind when I go shopping. What I'm most likely to come home with? Probably more focus fabrics. LOL!
