This fly is tied using only thread.  The darker abodomen, thorax and head  was made by coloring it with a black felt tipped marker.  I have also tied up some of these in just olive thread.   Another successful variation is a fly that uses red thread for the wing and tail with olive thread on the bobbin fasioned into the abdomen, thorax and head.

Last season I enjoyed fishing with flies made with just one feather.   Fishing with just thread, seamed like the next logical step in my simple fly experiments.

I have been experimenting with various wing designs and colors.  I have tied this fly in a variety of colors.  So far this one has been the most productive for pan fish.  I have been tying them on size 18 hooks.  I have fished  them on my fly rod (with reel), on a simple cane rod with no reel, and on a spin cast rod with a bobber.

I have also tied up some of these with 1-3 strands of flashabou or similar materials (No longer a "Just Thread" fly).  The flies with flash work well when the sun is bright.
