As a rule of thumb, and since there really seems to be no clarity on the subject. At FunWithFabric.com, we apply the word "Vintage" to anything that is prior 1980's. Why? Well honestly I don't know but it feels right. There are three common terms used in the pre-owned world "antique" (older than 100 years), "vintage" (normally older than 20 years) or "retro" (it references styles of the recent past). I choose to just use vintage.
