Hi I found a set of moose sheds and would like to fix them up so
what would be a good stain for this ? Also they have a couple of small
nicks from squirrels any way to fix them ?

Awesome! I am gonna look for some moose sheds this year when I am up there!! Not sure how to fix them but the guys on here (and Gals, sorry Michelle) will surely be able to help.

I make my own from peat moss , i take some peat moss and put in water for a few days, until it begins to rut, then i take hand fulls and rub it on, it gives a natural color to it.
The chews can be fixed with two part epoxy called sculpt all, or antler building epoxy, sold by most taxidermy suppliers, you want to fix them before you stain. Also antler stain can be bought from any supplier.

I like the pea moss because I can darkened bit by bit until I reach the desired effect.

Check suppliers at Taxidermy.net/forums

Awesom find Phil
Personally I dont add any stain to my antlers.
A quite a few years back I was told to use linseed oil on them to keep the natural color.WELL,I have done this to about 3 sets of mine and years down the road they started turning a yellowish look with a shine to them,not real natural to me.
And being sheds,I would leave the squirell nicks in them,adds a little more character as mother nature takes its role in the food chain.
Hopefully someone here will chime in and let us know how to bring the natural color back to a set of antlers as I have 3 sets to fix up

Thank you for the info Alex,glad you "chimed in"seems you posted the same time I did

Thanks guys I will see what I can do as with an estimated 48"-51"
spread I would want to fix them up.And thanks Alex with
the peat moss idea as I want to get them to look as natural
as possible.

You may want to spray it with hair spray lacquer over the stain and that will sealed the color in and not give it too much shine.
You can use some clear lacquer on the bases and burrs and let the pea moss stick to it, it will further the real look of bark and dirt.

Thanks again Alex I have seen some before with the bark and dirt look but
I din't know how they had done it.

Minwax walnut wood stain, no sealer. After dry, take steel wool and rub the points a little and the ridges and edges to lighten some areas.
