Curtain clips with elastic are available from Airstream on line, Inland RV, Vintage Trailer Supply. You can have curtains made by someone on this Forum, and I'm sure someone here will give you that information. I can't remember who it is that does that. You might check the Search option up at the top right on this page. Ambrose also makes wonderful replacement curtains for your unit. You can contact balrgn on this site for information on those because I believe he has ordered from them. You will enjoy the way your trailer looks with the original curtains back.
