I was certain I mentioned this, I use Krylon 1020, you can get it at Micheal's for $6 or $7 no sale no coupon post tax. When the can is nearly gone sometimes the nozzle has a bit of batting on it, but that just "picks" right off in a second or so. There are all different kinds out there, Joann's by far has the SMALLEST most expensive selection.
A bigger can is better because then you have it on hand for whatever you need it, for big and small projects (the big can will do two quilts full/queen, plus a bit). Once you get hooked that little can will look like a waste of money.
Once you find the right section, in any of the aforementioned stores (Micheal's, Joanns, Walmart, the LQS, etc.) look at all the different cans, be CERTAIN it lists that it's okay for fabric on the back and you'll be good to go.
