Matt,
Yes. It is cloth backing. The first bow I made had natural snake skin. It must have been past prime as the bow stinks to high heaven. I found a close match to it and it is a heavier cotton fabric. Goes on real smooth with TBII and takes the poly real well...I have some extra if anyone might need a piece or two....
I decided to go with the cloth backing as I feel it will hold up better in inclement weather, as I will be hunting Siberia and The Northwest Territories this year. Also Oregon. Wasn't sure how the natural skin would hold up to weather fluctuations, and I have a feeling the cloth will take the extremes much better....
