Gloves are only a problem if us anchor-bearers alone make a habit of wearing them, aye? If others join in, then we can hide in plain sight...as much as we can, anyway. Not perfect, but we don't get that most likely.

Or can your enchanters craft something magical to disguise them? I never thought to ask before, but that might work better than something that can rub off.

Either way, you can have another hand for testing if you like.
