Dave,
I am glad that you did so well at your craft show. I have never actually sold any work at a craft show, but it seems like you should have some items for oriented for spring time. Such as maybe BBQ grill tools, gardening tools, hose guides (basically just fancy little stakes that you put into the corners of your flower beds), plant hangers and holders, and maybe a weather vane or two if you are really ambitious. You could also try doing some camping utensils like meat forks and ladles to go along with your camping tripods. Don't forget that you would have to sell 40 $5 hooks to make the same amount as a $200 weather vane. That towel rack looks really good!
