Of all the blingy heat transfer films on the market, the ultra-metallic glitter-flake films seem to be the most appealing. We stock EnduraTex Bling, and Siser Glitter. Since these are 12mil (350Âµ) materials with lots of metal flake, itâs a little harder to cut and weed than a standard T-shirt vinyl.n addition to a vinyl cutting plotter, PC, and software, youâll also need a heat press. If your production goals are modest, you can begin with a small inexpensive starter press like the Geo Knight JetPress JP12 or JP14.
