Does this person often 'lurk' and read your posts, then pop up out of nowhere to protest them? Loudly?
I suppose they would be more difficult. There are a number of things to consider when building something that may be worn on a person's head for a period of time. I hear the british crown is so heavy that their monarchs have to get used to the weight of it.
And there are more materials involved in some cases than simply metal or gems... Very interesting indeed. I might have to do some research and sketch some designs out.
