Features 1、Made of soft silicone and good-quality plastic, durable and reusable. Organize threads and keep them tidy. 2、After using the spool hugger, just stretch the spool saver and hug the spool within a second. The spool does not need to be completely covered. 3、The bobbin holder can be used for most sewing and embroidery spools (except for large commercial or extra-large spools), which saves time to find small gaps on the bobbin to catch the thread. 4、These bobbin clamps are ideal for clamping on or off the spool. Convenient and practical. 5、When the bottom thread is not used, the bottom thread organizer is very helpful to prevent the bottom thread from separating. Prevent the bobbin thread from unraveling and knotting, and ensure that the bobbin is neatly stored and organized.
