Hi, I've tried to do research on this before but I've always came up empty. I started my own custom window decal business not too long ago and I've always seen companies with perfectly cut decals and never knew how they do it. They are all identical. I've tried using a big cutting mat with a blade connected to it. (The ones you see in art rooms.) Using this they looked a lot better but they were still different sized decals. I want my decals to look as good as possible so if anyone knows how to get perfect decals that are all identical let me know! Sorry if my wording was really bad and you don't understand what I'm saying lol.
