@Usa90 It's a bit difficult to explain in a text post. What I did was tie the knotting thread along the bundle of base strings. Tie first loop around the bundle, separate away one base thread, then finished the knot. Do the same in reverse when bringing the base threads back in. Keep counting the knots you need to do since it's easy to lose track, you can see how I messed up in some places on mine.
@Usa90 In my case, I used a trick. My base strings have the same color like the ears of the fox. On this point of the pattern I shaped my base strings.
@joeyjody@hiimtrinn you can find tutorials on shaped alphas on youtube. They basically work by hiding unused basestrings in the knots at the edges similar to how you would do shaped starts and ends.
