Hi Sharon. Yes, the BJ2000 is the fabric treatment so you can print right on the fabric (after you stabilize it with freezer paper). I would suggest you go with a fabric that has a little more substance to it (a 'high thread count' is recommended, but i've never been able to find that on the bolts of fabric). I use the Quilters' Cotton or the Kona cotton fabrics. When you hold them up to the light, they aren't as see-thru as the muslins (hopefully meaning they are higher thread count?).
i used it on the block that i sent you, if you want to see how it comes out (the one with printing in the middle that says 'i cannot count my day complete . . . ')
