Here is an otter, beaver and mink that I put up
All look pretty good. I would suggest some minor adjustments in your processing.
--Square off your otter butt and leave tail more natural like "Doug66" picture.
--Trim nose off of beaver.
--Lengthen mink and square butt at same time by following this put up procedure:
The following mink pelt boarding procedure will provide the greatest length possible for a mink skin along with dense fur in the inspection area. This is accomplished by putting the fleshed pelt snug on the board. Then, without any pining, with your thumbs on the lower belly and fingers on the back message the belly up and the back down. Then:
1) Grasp the butt end of the tail and lift up off the board an towards the tip of the board at the same time,
2) Now pull the tail down the board taut and pin in center of the board.
3) Then knead the tail upward along the board, making it shorter and wider and thus increasing the fur density in the butt area.
4) Pin the tail out in that position with cardboard or wire screen.
5) Now with a push pin grab about ½ inch of leg and pleat over to edge of the tail. Repeat until most of both legs are pleated onto the back side of the board forming a square butt.
6) The final step is to trim out the inspection window and cut off any excess leg remaining on the edge of the board.


I do my otter the same way as mink.
