The Kromskis make two styles of Lazy Kates - the arched version now comes standard with all Mazurka and Symphony wheels; the upright Kate comes standard with the Polonaise.
The Lazy Kates are very attractive and work just the way you want them to. They hold up to three bobbins. The bobbin rods are made of heavy metal.
These tensioned Kates will accommodate most other brands of standard bobbins including Ashford (standard bobbins), Jensen, Reeves, Timbertops, Majacraft and Lendrum (regular and very fast bobbins).
