Know the feeling. Did 6 shows this yr. Lots of lookers and compliments, very few sales. Only 3 of the shows did I make booth fee. But it's fun to do and keeps me out of trouble.
What finish can you put on coasters that will not leave a white ring after placing a cup of coffee or glass of water on them? I know shellac will not work.
I used 5/8 thick osb on mine with R13 insulation behind it and it dropped my inside temp on hot days from in the 100's down to the 80's.
I didn't bother to paint mine. I think the wood look is appropriate for a workshop
I've had an Etsy site for several yrs. During the year I have a few sales but not many. Between lat Oct and Christmas I sold around $200 worth but since then only 1 sale. Your not going to get rich but it's another outlet.
