Hi everyone, I’m fairly new here and don’t really post much so please don’t be too critical of my question as I’m always learning. I have received a very beautiful horse butt hide that has a lot of bending due to it still basically being in the shape of the horse it came from. The rump area is almost bowl shaped and sticks up when I lay it on a flat surface. Is there a way to flatten it or am I going to have to be incredibly creative when planning the project? Any advice would be great! Thanks
