I have suggested it before on this forum, it may have been me. I used it on a minky back to a quilt. Google it on you tube, there are several great videos. It worked like a charm on my quilt. I don't know how it would work on the "bubbles". It's used in clothing construction. It's not pellon, though pellon might have a tricot fusible interfacing. I just ironed it onto the back of the minky and it stopped the stretch. The interfacing stretches one way so iron it the opposite way from the stretch in the minky. What was neat about it is it can't be felt. The minky is still soft not stiff.
