Now that my season is pretty much over I want to try something different to beat the winter boredom. Anyone know where i can buy a thumbring ?

Thanks

I got mine at 3rivers. Read the sizing instructions and measure carefully.

I make mine.  Cow horn works very well.

Making one to fit your thumb might be your best bet. I'm sure you can find instructions how to at one of the horn bow sites.

I made a thumb tab out of heavy belt leather.  I also bought a thumb ring from Lancaster.  Both work and fit about the same though the tab is a LOT more comfortable.  I shoot nice tight groups. Unfortunately they're about 2' left of where I'm aiming!  I don't know what the heck is causing it. I'm shooting a RH Hill style bow left handed FWIW.

   They tell you how to measure your thumb so the ring will fit properly. Check out their bows also.

    Good luck with your new endeavor, I'm looking to do the same thing. Very intriguing!
