Eureka!!!

I knew if I kept looking, I would find it!! I have found the pattern I used as the basis for my Blackwork Caul!! It was on this website and I am pretty sure it is from the book "Medieval Craftsmen: Embroiderers", by Kay Staniland. 19981, British Museum Press and University of Toronto Press, Toronto, Canada. ISBN 0-8020-6915-0. I will check when I get home. I am SOOO glad I found this. Sometimes it sucks being an authentically oriented person.
