Keystones are bits used to include opulence to some thing of masonry or wood-working, bridges, structures or buildings. Doorways occasional contact about them in the layout at the same time, although keystones may be set on top of inside doorways, usually arched doorways. Keystones could be crafted from almost any hardwood. They are able to be trapezoids that are fundamental — which which will make up most of the keystones — or they are able to be trapezoids with moulding, carvings or overlay. The form must stay steady so alternative trimming or moulding can join at an angle onto the keystone from both sides.
