While hunting for frabic for new curtains for Pod, I ran across a fabric that is VERY close to the original fabric used to make the gold curtains in Westfalia campers.
Richard Atwell was kind enough to let me compare a sample I ordered from the manufacturer to his curtains.
Here is information on the fabric in case anyone is interested in buying it:
Manufacturer: Fabricut
Pattern: GHENT-F
Color: TUMERIC
Width: 54 inches
It should be around $30/yard.
