Can you use heat transfer vinyl/HTV on solid, non-porous surfaces. Rob put the puff vinyl designed for us on garments on a shot glass!!! The instructions are not only in our silly video, but are written out at the end. He then resined the shot glass with some holographic shards also offered in our shop. If you have questions, reach out to us at www.wesplurge.com or call us at 803-708-2000.
