IF I really love, love, love the fabric and can see it as a quilt back I will get 6 yds at least. If I think I will use it for a One Block Wonder or a background for some applique, I get at least 6 repeats or 5-6 yds, if I can afford it. If I just like the print and want to use it in patchwork with other pieces from my stash usually a yard or two satifies that whim. Fat quarters are my weakness though, I really don't have to have a project in mind for them, they are kind of like collecting pennies in a piggy bank. I get them because I want them!
Enjoy the stashing process! Sherry
