Hi! I recently attempted my first tan of a deer. I followed the steps listed here https://www.outdoorlife.com/how-to-tan-deer-hide-easy-way/ I am getting fur slippage and what appears to be a white mold growing on the flesh side. At the moment, it only appears around the outside edges so I'm hoping I can just trim it off but combined with the slippage I'm nervous the whole thing might be ruined. Does anyone have any advice about possibly achieving a positive outcome? Thanks!
