The initial books that was added to flypattern.org was the old, international known, salmon fly authors: Blacker, Kelson, Francis Francis and others. This coincided with the ASFI 2018, and was a natural starting point for the site.
The plan have always been to digg deeper into authors and flytyers that are known locally and internationally, and to document the patterns that these people are behind. One such author is John Sand (Norway), that together with his son Erling are well known for their patterns and the extended business they built.
Last year I was lucky enough to purchase a box of materials and hooks after a person that tied for the Sand company, among these were 3 hand-written recipe books from the time. At the same time Roy-Tore Gjertsen have been collecting and tying up the old Sand patterns, keeping a translation of them in English. Now there are 92 patterns added to flypattern.org, documenting the old patterns for the future, in addition Roy-Tore have allowed me to use his pictures of some of the patterns listed in order to get a reference version online.
I hope this can help preserve the patterns from Sand in the future: http://flypattern.org/authors/john-sand
