Thanks for all of the insight. So much is also local dependent, but that doesn't mean you can hose your customers. I do two venues a year one is a three day consignment event the three days after Thanksgiving across from a local vineyard. They get 20% so I mark my stuff up accordingly. They also help me with my pricing, they usually tell my prices are too low.
My other event is my annual Christmas fair at our church. I have developed a strong following there. An example one item. I stack cut 6 1/16 ply for the ornament below. It takes 45 minutes to cut, add finishing, signing and packaging = 1hr for six. I sell them for $12 each. My material cost each is .25 for the wood, .50 for the box. x 6 ornaments $4.50 $72-4.50 = $67.50 for an hours work. The profit margin on some of my more detailed and special items is not so high.
The second picture was at a small boutique owned by a friend that asked if I would do a small table as a trial last year. It was fun and I did surprisingly well for such a small venue. The plus is that I met a bunch of new folks and customers that will come to our local fair this year.( I hope)
