My First Wineracks Revisited

I've been thinking a lot about wineracks lately and I thought it would be nice to share my very first design. I started making these last summer partly as a hobby, and partly to make money selling them at the local farmers' market. They weren't a big hit so I move onto another design, but I think I should give these another chance. What do you readers think?

Do you like this design? I think it's simple, but functional.
