Everyone with a Schacht wheel raves about their Lazy Kate. It is a large, three bobbin Kate with a scotch tension brake to keep the bobbins and yarn under control. The bobbins from most wheels, including Louët fit on Schacht's Lazy Kate, making it a useful accessory for any spinner. Easy-to-take-along version that is simple to assemble and take apart. (Sorry but Majacraft bobbins are too big in diameter for the Schacht Lazy Kate.)
