First time pricing my work
I have been throwing clay for about 3 years consistently.
I pay for "open studio style classes" through our local community education programs. A cycle is 8-10 weeks, 2.5 hours of studio time each week. Class fee includes clay, tools, both firings and a stock of glaze.
located in MN
I have given away many items, but never charged or been asked how much I want for something.
a coworker of my husband's really liked a mug with a handle experiment that came our of my last cycle.
When I offered it to him, he said he would like to buy it from me.
what would a fair price be for both of us? He wants to respect the effort and skills I have been developing, but I also don't want to overcharge.
Might also be a touch of imposter syndrome 🙃
I would love to get some input from folks with more experience and an understanding of what it takes to create.
The cup in question is the first photo. I included the row of handle shapes I played with as well.
