No one is yelling at you. Well, no one worth your time or attention, anyway. The fact of the matter is, long before you needed the government's blessing to do ordinary things like fishing, and hunting, and making signs that you may or may not sell, America was a FREE country. You didn't NEED the gu'mint's permission to do much of anything. I don't CARE if you are a business, or a stay-at-home Mom who needs an outlet, like "Hand Painting Signs For FUN and PROFIT!" Speaking only for myself, I am glad you are HERE, and I know that SOME of the "professionals" here are more concerned about sharing what they have learned and helping you to avoid costly mistakes, than pointing at the "NO GIRLS ALLOWED!" sign at the entrance of the tree house.
Stringers are long, thin wafers of wood attached to the rear of a sign, to prevent it from warping in the damp outdoor weather. They are sometimes crescent-shaped, or they may be long strips of plywood, etc. They are usually only a couple of inches wide if that, and they are attached perpendicular to the rear surface of the sign. They work in the same way the webs of an I-Beam prevent the center web from bowing under a load. So the sign face cannot curve like a potato chip, because the stringers on the back side do not easily bend in THAT direction.
