Antler scale dryness test

[Tinker Simpleton]

When do you know that antler scales are dry enough to use for scales?

I've got a friend who wants me to use his antlers and I don't want to use them until I know they're dry enough.

Good question and I will be interested in what others have to say. My guess is at least two, preferably more, years.
