2 or 3 crowns in my opinion isn’t really a fair price, please don’t sell things for so little, value your work more than that.
I sell “throwns for a throne” (throwing daggers) and most of the brokers I’ve spoken to have said I could even charge more than that if I wanted. I also sell small bits of leather decorative tat for about a crown or so, or leather pouches for about five crowns.
Remember that first of all, you are spending time on each of these things, and time has value. Second of all, there are vendors who make their ooc living selling these kinds of things for real money, so don’t underprice stuff because it essentially ruins things for everyone (including you) if you push the price down too far.
Think about how much time you spend making them, as well as materials, and also the time you spent designing them, and the time you will spend on lugging them around the event trying to flog them. This is all stuff that has a value and should affect the price. The quality of the design, materials and construction is also important.
Remember that most of the things people spend money on at the game are temporary (food and drinks, ic resources, ribbons, rituals, secrets, services), whereas this is an actual item that they can keep forever even if their character dies.
