These shuttles are especially designed for Sakiori weaving. You can insert two kinds of Sakiori strips and adjust the position of the two pins inside the shuttle in accordance with the weaving width.
By making the distance between the two pins equal to your weaving the Sakiori strip will come out from the shuttle exactly as you need it, so you can weave very easily and smoothly.
The Sakiori Shuttle is available in two different sizes:
Length 43cm, Distance between the pins 13.5cm-40cm, Weight 172g
Length 55cm, Distance between the pins: 24cm - 52cm, Weight: 235g
