DOUBLELIN Sewing Thread Combo — Matching Top Thread & Bobbins
The DOUBLELIN Sewing Thread Combo includes 36 prewound plastic-sided bobbins plus 4 baby-size spools of top thread, 500 yards each. Bobbins and spools are wound in the same color and the same 40S/2 spun polyester thread, so your top and bobbin thread always match — balanced lockstitch tension with cleaner underside.
Size A, L, or M — Three Sizes for Different Machines
- Size A — Class 15 / SA156 / 15J / Size 11.5 (36 bobbins + 4 spools). Fits most front-loading and top-loading domestic machines.
- Size L — Style L / SA155 / Size 9.4 (36 bobbins + 4 spools). Fits Brother, Babylock, and other machines using L-style bobbins.
- Size M — Style M / Jumbo / M-Class (30 bobbins + 4 spools). Fits machines using M-class large-capacity bobbins.
Confirm your bobbin size first — sizes are not interchangeable.
