Slingr

Also known as bottle braiding, this is done with four or more suspended wooden bobbins or bottles, requiring two or more people to pass the bottles to one another in sequence producing a braid.

The simplest four stranded braid is still very much stronger than yarn or thread itself, and may have been used to make cord for fishing lines. More complex colourful braids can be made using more bobbins. As the number of bobbins increases the braid becomes more rounded in profile. The resultant braid is akin to modern Kumi Himo braiding.
