Fortunately, after over 30 years of buying fabric (good grief!) I have enough fabric of every color in my stash to make many, MANY quilts without having to purchase so much as a fat quarter!!
I also focus on blender prints, value of color, a wide range of white/ecrus/shirting prints on white, and very pale pastels. And I have enough large prints in many themes to create borders, backings, etc. Reckon I'm set!!
I try not to get too wrapped up in fabric shopping these days; there's just no more room or $$$.
