This product has been out for a year or so, but I hadn’t seen it until I came upon a video demonstrating The Soft Hackle Midge Emerger by Craig Mathews at Blue Ribbon Flies. I have been using the tying thread for the body lately and then ribbing with a single strand of contrasting tying thread or fine wire. This Combo Thread, if offered in enough variety might be perfect. I am not sure, by the look of the spools, if a normal bobbin can be used? Appears to only come in 6/0? Worth a look see at Blue Ribbon Flies. Also, for the beginning tier…look at how Mathews ties in and wraps the feather. In the process of thread torque around the hook, the feather fans out nicely, as if wrapped in the conventional manner.
