I recently bought a Mary Konior pattern book and this is an edging that I have done from it called Faith, Hope and Charity.
I decided to edge a handkerchief for myself to keep in my handbag. I have had the handky since I was a young girl back in the 1950/60's, but it has never been used....I'm amazed that is has stayed so beautifully white!.... and the thread is vintage Coates size 40 c...1960's
The pattern is just rings, but beautifully designed. There are no diagrams but it is well written and easy to follow.
