The first thing to do is unsubscribe from all those store newsletters. I have done that too. The second thing to do is learn a good method for binding and get those out of the way.
Put yourself on a BBB diet. Only buy fabric if you *MUST* have it for borders, binding or backing to finish a quilt!
Sort and organize everything. Hauling all your fabric out and sorting and organizing it can satisfy the need to just play with fabric without buying and adding to the problem. Plus when it's in a giant pile in the middle of the room you'll see new and interesting fabric combinations that'll inspire you.
