Clear stickers look great on windshields and other transparent surfaces, but printing your own costs quite a bit. With a little elbow grease, you can make custom clear labels for a fraction of the price.
You'll need access to a laser printer (inkjet printers won't do) to print your label on a regular sheet of paper. You'll also need clear packaging tape, a bowl of water, a spoon and scissors. Make sure your printed label is not larger than your packaging tape.
Stick the tape on the label, and use the spoon to smoothen it. Cut it with the scissors and soak it in the bowl of water for a few minutes. Once it's soaked, rub away the paper with your finger, and let the sticker dry. You'll have a clear sticker, ready to go.
