Roo does make a nice strop. I would think twice about the lazy Susan thing, but hey you might be onto something. You might be better to make several hanging or paddle strops from the roo you are getting, I have one leather strop, and that is a roo one.that I made.
All the best

The hide is cheap, and I want to buy more than I'll need in case of screw-ups (I'm not the most crafty person around) so having enough to give the rotating thing a shot isn't going to cost much.

But given all this advice I may just put the excess away for a bit, and see how I go practicing. The leather will still be there.
