Tentmakers have a monopoly on the production of tents and awnings, making pavillions for travelling nobles and stall covers for street vendors. Their basic product is canvas which they weave from flax and sell to shipwrights, mercantylers, and chandlers. Some tentmakers manufacture sails and deck tents for ships; some specialize in renting tents and stalls to those attending fairs and tournaments. A tent sells for around 3sp per square foot. Hence, a pavillion tent, the kind most common at fairs and tournaments, 10’ x 10’ (floor area) would cost about 30gp. Tents decorated with heraldic or other symbols usually cost more.
