Fusible batting NOT fusibel interfacing.
 

I have YARDAGE of fusible BATTING. Bought it when I was making totes and used it for handles. ???? can I use it for quilt batting WITHOUT fusing it the back?

Yes, you sure can. I bought a bunch of fusible awhile back but it doesn't fuse very well so I use it as regular batting.

Try a small quilt sandwich first. Check it to see what happens when it goes into the dryer. Wall hangings or totes should be fine.

Yes, I use fusible batting all the time so I don't have to pin or spray baste my quilt.
