Blue Dot Bobbin Case for Free Motion Quilting Bobbin Case
Bobbin Case for Free Motion Quilting (Cat C).
Pre-Set with lower tension, the optional bobbin holder has the same structure as your original one but with the tension pre-set approximately 40% lower helping to produce neater stitching on the underside of your quilts.
The lower bobbin tension also gives more control for improved results with such specialty applications as "Hand Look Quilting" and is also ideal for "Ribbon Work" where thicker threads are used on the bobbin.
The blue marking on the top of this optional bobbin holder allows for easy identification from the standard one which has a red marking.
For Janome Models which are Top Loading and have an Auto Thread Cutter .
