Three out if four
Nope
lol, nope
I deliberately didn't include any thing for sizing, Its about 6 inches, and not quite a ball shape
Its for holding something captive
Its Wool Cage.
I noticed that women in my Knit & Natter group allow their balls of wool to fall on the floor and roll around. They can put the ball of wool in this and attach the springy thingy to something. The wool ball is still free to rotate giving off its string of wool but it can't roll around on the floor getting dirty, stood on or tripped over
Its a test piece. I'll give it to one of the members, a volunteer, to try out next Wednesday at our next meeting
