LACIS-In-Line Yarn Ball Winder. Need a yarn organization solution or a way to manage your scraps? This hand operated yarn winder is perfect for making pull thread balls up to 4 ounces without requiring any cones or tubes. It uses an in line bobbin with a moving yarn guide and a removable table clamp, which gives the winder total control and a very smooth winding motion. Plus, there aren't any exposed mechanisms that catch yarn as you wind. Winder measures 5-1/2x8x3-3/4in and clamps onto surfaces up to 1-1/2in thick. Imported.
