Tape is an excellent graphic tool to create lettering. This amazing site called 'hand made fonts' explores fonts made out of all types of wierd and wonderful materials such as cookies, hair, dirt and styrofoam just to name a few. This is a sample of the font made from masking tape available to purchase from the site.
There are also a few other fonts made from different types of tape.
Here is the one made from brown packing tape. I think i could spend all hour, or at least hours looking at all the fonts here. Some of my other favourites include the fonts made from Toast and post-it-notes. you have to seriously check it out for yourself.
