You should also know a bit about that which you are claiming to sell. So, if you don't cook or know anything about spices, don't be a spice merchant. A slave may only need a fan or pitcher of water to serve their master, or a broom for sweeping. Think about the character you play and what kind of personal props you may want to help you better portray your character. You may only carry period weapons.
Turkish blades are of course acceptable.
I don't want to see weapons we may have traded for as that would take away from the overall look. No mountain men or civil war rifles, etc. Special care must be taken when handling weapons. Weapons must be put away after hours, unless you are rehearsing or practicing and you are not drunk. I highly recommend everyone who carries any kind of weapon to get some sort of training on how to use it.
