As far as how much fabric------If its fro a baby quilt, I'll get say a yard or so and add it to my stash. If its going to maybe go to a grown up or is an exceptionally gorgeous piece like the green that I used in my pansy quit, I will get several yardds--whatever I think the pocketbook can handle at the time. I like flannel for backing on baby quilts and will get a couple of yards whenever I get to the store and nothing else strikes my fancy at the time. I too tend to buy it for a project only to find that I "borrowed" it for something else :lol: I have so many ideas whirling around in my head sometimes its makes me dizzy :!: But take it from the champion worry wart, if you stress out about how much or whether to use it or save it for another project, it quits being fun. Just enjoy it and go with your instincts about color and design. Its not suppose to stress you out, that's called work and we already have to do too much of it :!:
