I am still trying to get down the whole epoxy tumbler thing and I have made a few and actually even sold 2 tumblers and have people asking me about buying some others that they want me to make.
These tumblers are a pain sometimes because there is such a long wait between steps, like HOURS and sometimes even days depending on how thick the epoxy is and how long you want it to cure before giving it or using it.
My first tumbler was a bit of an experiment since I was wanting to try the ombre effect and overall I liked how it turned out. It took me forever to decide what to put on the tumbler and the "enjoy today" seemed to work well with the colors. I used blue holographic vinyl and silver metallic vinyl on the little dots.
I did learn that the camofluage of the ornginal cup is hard to cover up even with a few coats of Krylon 2X paint and primer but it didn't show through so bad that I needed to strip the cut and start over.
I'll make some more posts when I get time of some other tumblers I have done and I will get posts made of those when I get time. I have a few on the racks right now that have the first coat of glitter and need to finish up.
