I’ll probably try that when/if it becomes necessary, but so far, the bands fit perfectly alongside the stretcher that I’m using, so I’m pretty sure that trying to use an additional one might be overkill, for now. If I up-size the stretcher at some point, then I’ll try it. I can also see your silicone sleeves being used for this, if shortened, or perhaps made for this? (yet another product idea, perhaps?) For sizes, I’d just use the retaining bands as a measuring unit, i.e. 1 band, 2 band, etc.
