For your first one that is really good. Just make your wraps on the chenille closer and that is about all I can say.
Some chenille will be easier to make look good than others. The Nylon is probably easier than Rayon. On the Rayon take it between your thumb and fingers and pull it through. One way you will feel it to be very smooth and the other a tad ruff. Find out which way makes the better looking jig and use it each time that way. I hold the ruff end and tie starting with it.

Good Job buddy,
