one time, long, long ago coyote fur prices took a dump along about mid winter. i decided to keep the furs i had put up until the following winter. i took each one and folded it in half length wise. stacked them all together and put them in a big plastic trash sack and then put another trash sack over that. double sacked. then i wrapped the bundle in a blanket. was trying to keep them from freezer burn.
put them in a chest freezer. next winter i took them out and they looked as good as they did when they were put in the freezer. sold them the following year with no issues.
