Kaleidoscope is a very versatile thread suited for embroidery, embellishing, even the overlocker. We recommend a Metallica needle for best results.From Beccas experience when using for 'free machine quilting' use a loose tension and invisible thread in the bobbin. Otherwise, unlike other metalic threads it doesn't just snap, it will stretch first! It is more like plastic and the thread appearance is flat rather than round.~~~964~1438~~
