My DH is one of the good ones, too. He does not complain about anything I buy for anything. We are in the process of closing in our back porch for me to have a sewing room (his idea.) He just ordered me a new sewing table (his idea.) He doesn't understand, but does not mind my obsession with quilting books/magazines. And he really does not care how much fabric I buy.
However ... he just does not "get" the stash thing! His comments are along the lines of why do you need this when you don't know what you're going to do with it yet. Just make anything you want to, Baby, and buy whatever you need to make it with then. I try to explain it to him, that for scrappies you need all these bits and pieces. He loves me and would do anything for me, but he just doesn't understand having a stash! Bless his heart ...
