Hopefully the mink is froze and not skun yet- it will be easier. If not do the best you can.
DO NOT cut off the nose- yo uwil lregret it! What yo uhave to do is "SKIN" our the nose and feet. THis means carefully leaving most of the cartiledge on the animal. Shave it with a sharp knife. On the feet- take your knife and carfullt slit each toe until the very end- then carefully 9again LOL) peel the toes out.
Then tan however you want.
