I am searching for a pattern that was on a Mountain Mist package probably 60 years ago. It was an tulip pattern...tulips in a vase...appliqued.

I remember it ,but don't have it will be watching other posts love tulips.

I found these books:

Edit: I found the first book on Amazon, but the table of contents does not indicate the pattern you are looking for.

I would put a permanent "search" on eBay for Mountain Mist patterns and just check them out as they are listed until you find the one you want.
