 I noticed already at this stage that the inflatables behaved very differently when you leave one side of the hard plastic backing on. It helps to control the motion into an upward movement, rather than a cringing, shrinking effect. In this video you can see all samples first with the backing still stuck to the back, and then again without any rigid plastic, just the soft vinyl.
