Here are a couple vintage sites, write to the gals here, and see if they can assist you in some way. I remember what you are talking about, but never had a pattern like that at all.
These sites don't always list what they have, you have to inquire about things, don't be bashful, the gals are very helpful.
Hope this helps somewhat.

I don't have the pattern, but I do know what you are talking about. My mother in law made them.
