We have started selling Big Muff using custom-made herringbone tape with navy blue thread.
The custom-made tape, which is a little harder than ready-made products and has a reliable feel, has navy blue thread, which can be said to be the symbol of Rare Gem, and gives a moderate accent to the unbleached body.
Custom-ordered herringbone tape with navy blue thread, it looks like this when enlarged.
The navy blue thread of the canvas used for call bags is straight, but the navy blue thread of the herringbone tape is slightly zigzag along the center of the "bone".
