Make Your Own Vinyl Signs
 

The most used sign material is one called a "Coro" sign. It is a plastic material that looks similar to corrugated cardboard. This material will last up to two years depending on the weather and the amount of sunlight. The material that is most used to cover signs is "Vinyl". There are many grades of vinyl. The lowest grade is called "calendared". Calendared vinyl will usually last three years or more outdoors. You don't need the more expensive vinyls.
