Frequently Asked Questions

Q

How much cord do I need per strand for kumihimo?

The standard multiplier is 2.5x the finished length plus 6 inches for finishing. A 7-inch bracelet needs about 23.5 inches per strand (7 x 2.5 + 6 = 23.5).

  • Round 8-strand: 2.5x finished length + 6" finishing
  • Round 16-strand: 2.8x — more cord per strand due to density
  • Flat braids: 2.3x — slightly less than round
  • Spiral: 2.6x — twist increases cord usage
Q

What is the total cord needed for a kumihimo bracelet?

An 8-strand round braid bracelet (7 inches) needs about 16 feet of total cord: 23.5 inches per strand x 8 strands = 188 inches = 15.7 feet plus 10% buffer.

  • 8-strand bracelet (7"): ~16 ft total cord
  • 16-strand bracelet (7"): ~37 ft total cord
  • 8-strand necklace (18"): ~40 ft total cord
  • Add 10% buffer for waste and finishing

Q

Which cord material is best for kumihimo?

Satin rattail (2mm) is the most popular choice for kumihimo. It braids smoothly, comes in many colors, and costs about $0.05/foot.

  • Satin rattail: smooth, shiny, best color selection
  • Nylon: durable, good for everyday wear pieces
  • Leather: premium look, $0.12/ft, stiffer to braid
  • Cotton: soft, rustic look, $0.03/ft
Q

How do I set up a kumihimo disk?

Place strands evenly around the disk in opposing pairs. Color placement determines the pattern. For 8 strands, place 2 at top, 2 at bottom, 2 at left, 2 at right.

  • Load strands in opposing pairs (N/S and E/W)
  • Thread all strands through the center hole
  • Attach a weight (washer or bead) to the bottom
  • Move strands in the kongo gumi sequence: top-right to bottom, bottom-left to top, rotate
