Hello Jack
No-one can know how you stand financially but I thought I'd offer the other side of the coin for you to peruse. You see I've been there, done the craft fairs and dumped the Teeshirt, thank you very much.
Setting out to only make stuff that sells rather than what my creative juices suggest became a real bore.
Setting the alarm clock on a Sunday morning, loading the car, carrying the trays of goods into the venue, setting up the stall and than standing back to listen to the ladies billing and cooing over the stuff while giving turning advice to their hubbies before repacking etc, etc, etc just wasn't for me, no matter that my stuff seemed to sell well. I suppose I just wasn't hungry enough
Now I prefer to work with freeby wood and turn what I want, when I want and keep only what I want while sending the rest off to the charity shop.
Hope that's of interest and best wishes with whatever you do.
Brian
