Double holder adapts large size spools and cones for use on domestic sewing machines.
Larger spools and cones of thread are too heavy to sit on your domestic machine’s regular thread spindle. The drag created by these large spools and cones messes up your tension for poor stitch quality and broken threads. Works great for double needle sewing too.
Collapses easily to fit into your travel sewing kit. Double cone design. Suitable for 1000 meter – 5000 meter thread cones.
