I buy fabric I like when I see it because it may not be there again when I want it. Fabrics and fabric lines are constantly changing. My SIL who quilts told me if you like it, buy one yard: if you love it, buy 2: if you REALLY love it, buy three. I have found that to be good advice. My stash is not large but I know over time it will get bigger. I just love fabric shopping! :D
