Take a length of roving (50cm (19 ") is a good length to work with, you can always add more) and, starting in the middle of a row, bring the roving up from the back of the weave leaving a tail of 5cm (2"). Wind the roving around one warp thread to secure it.
To make the first row take the roving over six warp threads then loop it under and back between the 3rd and 4th warp threads.
Repeat Step 2 across the weave. Vary the amount of warp threads you weave the roving across and through to vary the shape and size of the soumak.
Bat the weave down when you reach the end of the row. Turn and repeat back across the weave the other way.
The soumak will also vary in size depending on the thickness of the roving – as it gets nearer the end of the length, the soumak will gradually taper away.
