So I'm fairly new to layering vinyl to create more complicated stickers. I've done 3 layer designs and its been great with transfer tape. I want to do badge overlays for vehicles (oval badge overlay) and when other stores sell these they do not come with paper/plastic transfer tape. These are layered vinyl (not printed) and are easy to apply because they don't have the transfer tape. How do they layer the vinyl? Do they use a low tack transfer tape to assemble the sticker and then discard the tape? Thanks for your help!
