Like "Nanna up North" I have a decent stash, and could make a small baby quilt or scrappy lap quilt if needed.
When working on a new project I may need to buy a few new pieces for that particular project, but I try to take from my stash as much as possible.
I do, however, collect FQ's of greens, as I love applique and there are never enough greens as far as I'm concerned. Once in a while, if there is a spectacular sale on, I might treat myself to a yard or two of something that catches my eye.
Lately with the cost of fabric increasing, I find that I have to be more careful about what I buy too. No more spontaneous spending going on around here.
