If anyone wants to add frets to this pattern, what I did was take the light grey/silver and used that to replace the brown knots in rows 10, 13, 16, 19 and 21. I'll upload a picture of what mine looks like when done, I'm doubling & mirroring the pattern to make it longer.
adjust the colors to fit any variation, my variation seems to be the original with a red background and white guitar body.
@jackstorm The How To Make Alphas video should tell you but you either do forwards backwards knots (when going left to right) or a backwards-forwards knot (when going right to left).
