Why a stash? Hmm... I guess because I've already experienced finding a fabric I like and then having it discontinued. Plus, since hubby offered... I don't mind buying fabric as I go, but sometimes there are great sales and I'm tempted to buy at the sale prices. Last weekend was a holiday sale and I bought a quilting book for 50% off but no fabric because I wasn't sure how much. If I buy it as needed, I'm missing out on the sale prices and I am kind of thrifty by nature.
Sorry for the long response. Just thinking aloud here. Thanks for the suggestions!
