I never know quite what I'm going to do when I sit down, although around here I've had the most success on more naturalistic flies, especially stonefly nymph-based patterns. So I knew I'd do something like that. Black also seems to work well, so I had this one more or less in mind.
Then I found some funky orange yarn way back in a drawer. Think October Caddis.
Can't wait to throw them out there.
