Here is a picture of the supply's.
Start by laying the thread down the hook shank.
With the thread down the shank, start at the head and cover your thread towards the hook and back to the head with the thread in the bobbin.
Trim off the excess if you have any. Don't cut the thread in the bobbin though. It stays the whole process.
Get a piece of your chosen feather and trim as much as you want for your jig. More feather the fuller but not necessarily better.
Place the thread on the shank and run your bobbin of thread down towards the tail and back to the head. I usually go about the middle between the hook and head.
Here is running the thread down the hook and back.
When the thread is back to the head it will look like this.
Repeat this process until you cannot see the hook shank. Or until you like it.
Place the chenille starting at the head and running towards the tail, then run the thread down the chenille to the tail and back to the head.
Here is running the thread to tail and back.
With the thread to the head start wrapping the chenille around everything all the way to the head. Hold it tight when you start wrapping your thread to secure it.
When you wrap the thread start on the hook side to secure the chenille about 10 wraps. Then go to the head or outside and wrap till it looks nice. When finished cut the chenille
This is how the whip finisher is placed. Like a number 4. You can also tie 3-4 half hitches to secure this.
Here is whip finishing in action.
Lastly put glue on the thread only, not the chinelle around the head.
