Our tensioned lazykate has a blackwood base and stainless steel rods for your bobbins. The nylon line runs around the bottom groove on your bobbins and tensions similar to a scotch tension on a spinning wheel. All of the rods etc are easily removed for flat storage/travelling. It fits up to three of the most regular sized bobbins(Ashford, Peggy Sue etc). Please contact us with your bobbin size if you are unsure and we will let you know which one best suits or will make it to order.
