If I want fabric as a focus fab and as borders, I buy 4 yds since I like a wide border. I ususally try to buy fabric to go with pattern all at one time since that way I have enough of each fabric. ( or only what is needed.) I am not a great stash builder since I never seem to have the correct or right amount of fabric needed in my stash. If I am buying "go to gether fabrics" then I buy at least 1 yd of each. I also put fabric together with pattern and wright which goes where so I do not forget.
