Thanks guys. I had a rough idea about the shape but basically started with a rough sketch and made it fit my mitt.
Now I am going to start one to match my Black Widow PSAII and hopefully finish it before I leave dad's workshop in 6 days.
Though hunting is the first priority after spending time with the family, so I may just have to do what I can and finish it at home.
Thanks again, this site is an incredible resource...
