Do you experience too many thread breakages or "bird's nest" of your bobbin thread when sewing?
One way to reduce those thread breakages, snaps or uneven tension when the bobbin spins and gives a "bird's nest" effect of thread on the under side of your fabric, is by using a special pre-wound bobbin with a Magnetic Core. These are made by Fil-Tec and called Magna Glide L STYLE - CLASS 15
This bobbin has two flat sides and is available in metal, and as a Magna-glide core.
The L Class and M Class bobbins are substantially different in size. Machines designed to use L Class bobbins will not accept M Class . Thread is same as Fil-Tec 40wt thread
Remember to remove the anti-backlash spring from the metal bobbin case prior to use.
DECOBOB the bobbin of choice for convenient hand piecing!
Why do Quilters love this 80wt Bobbin thread for piecing! It is a fine strong thread that disappears into the seam not creating bulk.
