First, sorry for the less then perfect photo. Second, this is a good dark caddis that solves the problem of split wings on tent style caddis while using good old "throw out" material. Take some used "dryer sheets", mark it up with brown or black sharpees, back it with some clear tape and then cut it to shape. Take a hook between size 14 through 20, dub on a grey or olive body, wrap a brown hackle over the first third of the body, trim the hackle off the top and then tie on the taped wing. Dub on some black (or your color) material for the head and then you have it. The dryer material gives a great impression of the veined wing. Tape on one side only and have the taped side so it's on the top of the fly. It will last forever and trout love it.
Try it out!
P.S. Double click the photo to get a better look.
