I have heard of 2 ways to save the velvet on deer horns. Take them to a taxidermist thattans deer hideschemically. Have them put them into the vats. The second way isput a tiny X with a sharp knife on the very tip of the antler points. Then use a hypodermic needle and inject formaldehyde into the blood vessels at the base of the horns and force all the blood out of the antlers to the tips,through the incissions made on the tips. I haven't seen the second idea tried, but the first works GREAT. My dad has a nice 8pt mount done with the velvet on them and itlooks justlikewhen he shot it.
Good luck.
