The hex's are being joined using a modified version of the flat-braid join, with two neutral colors. Now I have to decide how I want to make the edging, and whether or not I am going to use half-hexagons from this style motif to make the sides straight. Hmm... I think I will figure that out later, after I am almost finished with the hexagons.
