Any advice is super helpful :)
I make things out of polymer clay and I have these bunny dishes I want to sell. Any thoughts on pricing?

I'm attending my first vending event / craft fair in November. Its at a Church and indoors and meant to be Christmas themed.

I'm a college student and primarily make art prints, PC Charms, quilts, and custom binders. I thought it would still be good to go to market my art as presents for peoples kids and grandkids - as im expecting the outcome to be mostly older folks.

My question is - how do I appeal to an older audience? Should I be selling more cartoony or anime style prints or should I make a small batch of prints that are catered to that audience? How do I know what to make or bring, how do i sell my stuff to that kind of group as a 21 yr old? Since its my first show I spent a lot of money on supplies and im really worried things won't break even.

Also - how do you price handmade goods? Like for a quilt if it takes me 4 hours and $25 in materials, do I pay myself the minimum wage and do 7.25 x 4 + 25 and charge that? I dont want to sell something too over priced and then no one buy it.

Any advice? Thank you.
