I will check these out. I have heard of Timtex, but have not seen it in the fabric shops, I do know they carry Deco Bond, but not sure about the fast2fuse. I read where someone had used Warm and Natural for the fabric boxes, but can't remember how that worked in terms of holding the shape. Some quilt the fabric for the boxes, and some don't. I plan to quilt mine, at least the first one
, so I guess that would have have to influence the choice of batting.
