I'm looking for some tips on rigging a paddle strop until I can afford to get a nice one from Tony. (Next month...) I have some 1 and .5 micron paste on the way that I want to start using.

I've read about using balsa wood or cardboard. Should I attach this to some kind of backing?

I don't want to spend a lot of time on this, since I'll probably toss whatever it is when I get my two-sided paddle from Tony.

Thanks,
Josh
