Large Spool Embroidery Machine Thread

For 200,000 stitches, a 5000m large spool is recommended. A 1000m spool yields approximately 100,000–150,000 stitches depending on stitch density and design complexity. The Isacord 5000m spool provides enough thread for most high-volume production colors without interruption, making it the preferred choice for commercial embroidery houses running large stitch counts continuously.

Embroidery thread spools commonly come in 1000m (small to mid-size, ideal for color variety and sampling), and 5000m (large production spool for high-volume use). Isacord offers both sizes across all 390 colors. The 5000m spool weighs approximately 1 lb and measures 6 x 3 x 3 inches, while the 1000m spool weighs 0.5 lbs at 4 x 4 x 3 inches.

Isacord embroidery thread is a 40-weight (40wt) thread, which is the most widely used weight for commercial machine embroidery. The 40wt designation balances coverage, detail, and running performance on high-speed embroidery machines. It is a 100% polyester continuous filament thread with a modified cross-section fiber for rayon-comparable shine.
