I picked up a heavy weight, fly plaid and flashes in the Free Mason tartan at KiltMart a little over a week ago. Were I not a Mason (and a past master at that) I think I would have picked it up anyway. It is very attractive. As a Mason I would take no more offense at a non-Mason doing the same than most would take at someone wearing a tartan based on appeal rather than clan affiliation. Good lord guys, the thing is only a few years old. How can it be steeped in mystery or tradition?
