• Etched Glass Window Film: The version linked here uses water to cling to glass, which makes it repositionable, removable, and amazing.
• A printout of the letter you want to use.
• Transfer paper (or any other means of getting the design on the backer)
• A craft knife
• A frame with glass or plexiglass
First cut off a small piece of the film, remove the backer, and set aside. Lay your letter template on top of the backer with a piece of transfer paper in the middle. Hold your stack firmly and trace all the way around the letter.
When you have your design on the backer, reattach the film by smoothing it down with your thumbnail until it it well attached. Using the template lines you can see through the film, cut the design out carefully with a craft knife, then remove the backer.
Follow the instructions included with your film to attach it to the frame’s glass. (I put a thin layer of water down on the glass, laid the letter down, and used my nail to smooth out all the bubbles.)
