Window Drapes Fabric Weight

[richard5933]

Starting to make plans for sewing new drapes for both ends of our 1994 Excella to replace the OEM drapes currently in place.

I've read through lots of threads about this and can't find any mention of what the original fabric weight was that Airstream used.

For anyone that has sewn their own replacements, what weight fabric did you find to be a close match to the factory drapes? I'm probably going to order the fabric online, and it's often referenced in terms of X ounce weight so if anyone has a reference to this I'd appreciate a little help.
