Hey I have some questions about table strops.

I've got some nerve damage in my left wrist and arm.
So no more shaving with both hands. Also I can't really hold the strop tight so well.
I'm wondering about table strops.
Did some searching of posts but can't seem to find the best option.

Can someone direct me to the thread or perhaps describe to me the best way to build a table strop?

I remember seeing one that Tom has a few years back, leather stretched across giving a perfect bow.. easy to use..
Should probably add cheap to that equation.. hehehe

Thanks a bunch!
