50 gram ball of cotton space dyed singles slub yarn. Approximately a 5's count, but the thin section is about the size of a 20/2 cotton. Approximately 480 yards in a ball.
It will give you a flat cloth used as weft, but you can add twist to make a lively cloth. Or you can ply with it to make a balanced yarn.
You only need one ball for weft to weave a scarf 2 yards by 7.5" wide, beating at 32 picks per inch.
On the second image, I wound it around a 7.5" card and the slubs did a pretty regular diagonal.
