I'm on a fabric diet as well, at least until the end of the year. So far I've gone into my favorite LQS and visited a quilt show. Total purchases: 1 set of rotary cutting blades and a loaf of Zucchini bread :) (courtesy of the quilt show bake sale!)
I have looked at a few of the fabric sales here on the board and just said "no". honest. You too can do it!!
Buy the prettiest pair of decorated pink rubber gloves, and on the day your moratorium is over - hand them (gift wrapped) to Mr. Smartypants on your way out the door to the LQS!!
