Thanks guys, the coin is pretty common over here - half crown was legal tender till two or three years ago and is still widely used by card players. The owl feathers come from a sanctuary for wounded birds, where a small donation got me 2 feathers = several years supply.
I tied these flies with Jizera grayling in my mind - I am heading that way over this coming weekend. A few jolly Scottish fishermen are coming over + reliable reports tell me that over by the whisker's place the splashes from rising fish are so loud that they can be heard from a passing car even with windows shut and radio playing. I can hardly wait
Cheers!
