For me, it's quilt backing. I like to make pieced backs - do a little something special, but I hate to buy that many yards of fabric if it's not on sale. Right now, I have to wait until August to get the back I want from Connecting Threads unless I stumble over just the right thing at the right price. I've only bought 1 template, which I will probably never even use - they are often way too expensive for being a one trick pony.
