Thanks to its long, durable fibers, flax linen cord has been used for centuries as a strong and flexible sewing support. Manufactured by Conservation by Design in the UK, this 100% flax linen cord is available in several plies depending on the amount of support you need. Sold in 15-yard lengths or by the spool (approx. 175 yards). Compare with MDL and Garniture flax linen cord.
