144 prewound Size A (Class 15 / SA156 / 15J) plastic-sided bobbins, wound with 75D/2 filament polyester thread in White. High-yardage industrial bobbin thread — perfect for large embroidery runs with fewer bobbin changes.
Embroidery stitches fully cover the bobbin thread — so white works on any fabric color. The 75D/2 filament polyester gives you ~150 yards per bobbin (about 1.5x a standard 60S/2 bobbin), meaning less downtime changing bobbins during large designs or production runs.
Decision Guide:
Most embroidery, any fabric color → White 75D/2 (this listing)
Dark sheer fabric → Black 75D/2 (APB-75D2)
Need more strength → 60S/2 or 40S/2
Sewing & Quilting → 40S/2
75D/2 is a fine filament polyester thread. Your machine must have adjustable bobbin tension for optimal results.
