The joke's on me.
It didn't take long to realize that this idea was a bust. The yarn is made up of 6 tiny cotton strands that ARE NOT twisted together. Not at all. So it quickly becomes a stringy, tangled, useless mess. Imagine unravelling an entire sweater's worth of kinked DMC embroidery floss.
Oh well. Only $2.00 wasted. Good thing I didn't buy a yarn ball winder. Maybe someday.
