Sprang is a twisting technique.
Basically it is yarn warped between 2 rods. The lower rod needs weight
added because you want tension. That can be a set of keys or even a shoe.
Because the yarn is around the rods it creates a front and a back side.
The basic technique is that you twist the next yarn from the back, around the first one in the front. That is it. Your
You can add a yarn or a stick to prevent the row from un-twisting. And
to separate the front from the back.
It takes up half of the materials like crochet or knitting. And it goes
twice as fast.
