144 prewound Size A (Class 15 / SA156 / 15J) plastic-sided bobbins, wound with 60S/2 low-stretch spun polyester thread in White. The default bobbin choice for embroidery — works on all fabric colors because embroidery stitches completely cover the thread.
Embroidery stitches fully cover the bobbin thread on the back of the fabric. Unlike sewing and quilting, the bobbin color is invisible — white works on light AND dark fabrics. You only need colored bobbin thread for sheer fabrics or very open designs.
