There is a huge difference between glitter vinyl and the glitter plastisol transfers. I've had some plastisol transfers made and though they are "sparkly" they arent at all like what you can get with a cut vinyl material. I've used both Siser glitter as well as Stahls glitter flake. Glitter flake is crazy reflective but its very heavy. The Siser glitter is a nice balance between how shiny it is and how think the material is. I use that for most of the glitter stuff I need, though I dont do much glitter in general.
