Printable clear labels are quite pricy and often not available in small quantities. But there is a easy way to produce your own transparent stickers using packing tape.
Step 1: Supplies + Tools
Laser print or copy of your motive (The maximum width or height should not exceed the width of your packing tape)
Clear packing tape (I used tesapack® strong 66m * 50mm)
Bowl of water
Step 2: Transfer Print to Tape
Stick the packing tape on top of the motiv. Use the spoon to rub the tape against the print to make sure that all the toner sticks to the tape.
Step 3: Cut
Roughly cut out your motive.
Step 4: Soak
Put the cut out motive into the bowl of water and let it soak for some minutes.
Step 5: Rub Away the Paper
Use your finger to rub away the paper. Keep on rubbing until all the paper is gone, sometimes it goes easier when you wet your finger from time to time. Let the sticker dry. Don't worry if the sticker doesn't feel sticky, it will stick again when dry.
Step 6: Use It
When completely dry, you can stick your sticker wherever you want, e.g. on a glass jar.
