The team at Semperfli decided to develop their own silk range, however they wanted to do this as sympathetically as possible to the traditions of these patterns. Edmonds and Lee – Shades of Silk. The Semperfli team were very luck, finding a copy of the original 1000 trade edition copies of the Edmunds and Lee Brook and River Trouting Book at an Auction. Virtually unused and unopened a fantastic book in the Semperfli Library. One of our team also had been left a box of fly tying materials from a relative, unopened since the 1960’s, in that box were some traditional spools of Pearsalls Silks, referred to by Edmunds and Lee. This sparked the team into action. Working with a silks specialist and the Semperfli Pro team we decided to match the colors of the original Silks against the Edmunds and Lee Shades of Silks color chart. Although obviously, color pantone technology was not as accurate when the book was printed working with some specialists on the Semperfli Pro Team who specialized on Northern Spiders and Clyde style patterns we were able to look at historic patterns and match the colors against our dyes. The results a set of twisted pure silk threads that are as close match to the traditional silks as we could get.
