This bin is usually used by 3-4 children at a time, so I made 4. I wrap around the back of one of my bar stools. It's 16 inches across, which will give me (4) 4 inch poms. The yarn slips easily off these chair backs for tying and cutting. After cutting, I just give them a little hair cut to even everything up. I save the bits of yarn for another sensory bin filler.
They turned out really cute and the children really liked playing with them.
