Thanks very much everyone.
I'll do my best to explain this without writing a short novel Jonathan.
The stamp is made from a bit of 3/16 off-cut. The face was slightly domed, then gouged with whatever fell to hand, and then finally hit with a scotchbrite wheel to soften any sharp edges. I stamp from the left towards the middle of the sheath, overlapping the the stamping as I need to. I then move down about the thickness of the stamp and repeat from the right to the middle. Going just past the middle of the sheath with each row looks best. I repeat the alternating rows all the way down the sheath. To finish off I use the lip of the mushroomed head to create a line that takes each row past the center a bit further. I do this to soften and camouflage the abrupt impression the end of the stamp leaves. As with other patterns the boarder tool frames every thing.
Staining is fairly straight forward. A cap-full of London tan with a couple of drops of black in it to make a nice brown is applied liberally over the hole sheath. Let that sit for 10 mins or so and then using the brush in the pic I apply several light coats of black over the high spots. The brush needs to be only "just wet" or the darker dye will run. I find the best way to apply the darker dye is to lay the brush parallel with the face of the sheath and use the sides of the bristles rather than the ends. When I am happy with the contrast between the high and low spots on the front panel I re-stain the rest of the sheath with black of very dark brown.
Hope the above makes sense and the pics help. I also regularly use the stamp to make vertical lines instead of horizontal ones. Quite effective at creating a very convincing Antler pattern.
