To those who can ty down to #32 you just confirm a theory I have had for some time. That is that your day job must be as a retina surgeon! I wish I could see as well! I mean, when your fly is on the water, do you really know where it is........? Just kidding, my hat is off to you guys.
I tie pupa patterns down to a 26. I don't tie dries but the smallest midge adult patterns I have are #22's. I don't think I could see anything smaller than a #26 on anything but slack water.
