There are several ways you can "antique" fabric. Basically you can soak it in tea, coffee, or tan dye. I actuyally prefer coffee since it gives it a brown look. If you use tea make sure it is black tea since other types will give it a red tint. It may be hard to get navy to look old but the gold should be no problem. Of course test fabric first to see which look you like best. an easy way is to use ritz tan dye in the washer. you can either pre dye the fabric or dye the whole thing after it is done. Either way fill a sink up with hot water and about 30-50 black tea bags or lots of instant coffee. Let the tea bags steep for about 15-20 min and then soak the items until the desires color remembering that color is darker when wet. You may be able to do search on "how to tea dye fabric".
