This evening, I decided this evening to explore Russian fly tying and made my way to Vladmir Markov and Igor Tyapkin. In the process, I found this interesting little mouse pattern by Günter Feuerstein called the Minky Mouse. You would have to find straight cut and cross cut mink and some foam. I have never fished a mouse pattern for browns, big bows or grayling. I would appear to be a good beginners pattern for a top water presentation.
