I love the look of a snake knot keychain, but my first attempts seem to leave small gaps between the individual knots and overall does not look "smooth" for lack of a better word. Also, the completed knots look smaller in diameter than those shown in videos. Am I over-tightening the cord or failing to pull the cords in the correct directions when tightening? Any help or tips would be appreciated! Thanks!
As you pull the knots tight try pushing them closer to the previous knot. That should take care of any gaps. Also try and use the same amount of force every time when tightening the knots.
