One of the things I did for the craftshow, and didn't sell well either, was the double wall wine tumblers. While I only sold maybe one I still have to say I love these and love the designs I did.
Left: "Wine a little you'll feel better" I used a hot pink vinyl and a glitter vinyl and the Samantha font was used for the lettering.
Middle: "Feet Up Wine Down" I can't remember the font I used but I like the pink polka dot vinyl on the flip flops.
Right: "Wine Drinkers Make Grape Lovers" my friend Karen found this one on the internet and we fell in love with the saying.
I think most people probably know by now, but just in case, I found these particular tumblers at the Dollar Tree and while the quality isn't as good as the Vin to Go they are still okay.
