Etsy Shop FAQ
Templates are resizable! However, depending on the tumbler you're resizing for, there could be some distortion. You would just need to measure the height of your tumbler and around (for the width) and size your template to those dimensions.
If you have the Basic version of Silhouette Studio, I am more than happy to email you the Studio3 files for templates that you purchase when I return.
If you are using Cricut's Design Space and wondering about the black square, that is supposed to be an outline to cut a straight edge around your template. All you need to do is select "attach" and everything should be good to go! I always recommend doing a test cut on plain paper first!
