Optimize your bobbin tension for bobbin work, free motion quilting, and/or thread painting with our specialty/low tension bobbin case. The red dot allows for quick identification as JUKI's Low Tension Bobbin Case.
For sewers and crafters, it allows a broader range of creative freedom with decorative stitches by adding the ability to use heavy threads or light cording in the bobbin.
For quilters and crafters who like free motion quilting or thread painting this reduced tension bobbin case allows for easier balancing of tensions. Quilting and thread painting are art forms to laydown thread and create a "painted" scene or add interest with stitching through layers of fabric and batting. Tension when quilting or thread painting should be reduced, as the need to secure the fabrics together like a seam is not needed.
