Here's a new pattern I'm looking forward to trying next season. I've used a piece of foam wrap for the wingcase. It floats well and is easy to see. These are size 16. These little beauties will still nicely in the surface and won't need any floatant. Well that's the idea. The top photo is my second attempt. #18 this pattern represents the swimming mayfly emerger. The adult has speckled brown wings, so I chose a soft speckled hen feather for the emerging wing with a touch of CDC.
