@LiliaKnots it is basically the same technique used for the shaped evil eye bracelet. Alex's Innovations has a video on it.
Basically you leave out all the knots that are blue in the pattern and hide the unused base strings in the edge by making the first and last knot of each row around those unused strings too.
@Brooke1683@_Theatre_ I have a Boston terrier, I think that would be so cute! The creator of these patters are getting so many requests I can’t imagine 😅
