A simple caddis pattern added to the trout fly page. This pattern is only 4 materials and one of them being your thread. I've had good luck with the pattern on both the ozark spring creeks and in the Driftless Area. You can easily change the colors to match the hatch and you can tie a dozen of them pretty quick. It's a box filler, easy to tie, quick to tie and catches fish. Here's the link.
