12 wt./3-ply Spun Polyester thread.
Available in 50 bright, bold solid colors.
Recommended Needle and Tension SettingsHome Machines: Topstitch #100/16. Set tension to 2.0
Longarm Machines: #21 (MR 5.0). Reduce tension as necessary.
I used a Topstitch #90/14 (didn't have the recommended #100/16), and did not change the tension.
Liked it so much, I tried hand sewing with the thread
