Vintage and antique are two words you hear a lot when discussing DIY projects. But there is a distinct difference. To be considered antique, an item must be at least 100 years old. To be considered vintage, something only has to be 20 years old. Original pieces that were not duplicated can be worth a lot of money. Upcycling antique furniture has become incredibly popular. Upcycling can consist of refinishing an item or reupholstering it to breathe fresh life into it.
