Bill,

It's tied on a tmc 2488 size 20. You can tie a small larva and still have a
relatively large gap with that hook.

I use red 8/0 and bind orange rod wrapping thread to the top of the shank
with the tying thread. Wrap the tying thread back up to behind the eye and
half hitch it, then twist the rod wrapping thread tight by spinning it
counter clockwise then wrap it forward carefully, leaving just a little room
between each wrap so the red can show through a little. Glad you like it.
