Thanks! This definitely helps --ruth Roxanne said:It probably depends on the weight of the yarn. I wound 2 strands of baby yarn together out to the edge of the cone of the winder. I didn't put it on a scale, but it did not feel too heavy and the handle was still turning easily. I m sure a thicker yarn would take up more space so you would not get as many yards on it. Since it says 10 ounces, I would try to stay under that so the winder would last longer.
