DMC

DMC embroidery floss is worth looking at for tying tiny flies

I saw the idea in a midges book a year ago, but just got around to stopping
at a crafts shop.

Comes in a huge variety of colors, and a single ply of the 5 ply thread is
certainly small enough to body a 24 or 26 hook ... and it's cheap, I got 10
colors for about $5

If you fish tailwaters where midge lava and pupa are very important ...
check this stuff out I'm also going to try using it on 22 baetis ties, I
think I can get a neater body than with dubbing and better color than just
tying thread
