I created these templates with the intention that you will use them for fun personal projects, like mail art and/or gift tags. Please do not re-sell the files — not that you would, but I have to say it! These printables were made to fit standard-sized US printers (8.5″x11″); however, they should print just as well on non-US printers.
If you are printing the templates out with the intention of tracing them, regular printer paper should work just fine. However, if you are printing with the intention of coloring/collaging, I would recommend printing on 70-80 lb. drawing paper that has been cut to fit your printer.
