TandyPro® Thread Rainbow Set

I was pleasantly surprised by how smooth this bonded nylon thread runs through my sewing machine—no fraying or tangling at all. That German silicone oil really makes a difference for keeping the tension even during long projects.

The colors are vibrant and the silicone oil in the fibers makes it glide through my leather like butter. I've already reordered two more sets for my workshop.

I've been using this bonded nylon thread for leather projects, and the 4% Fi-100 silicone oil from Germany makes it glide through tough material without fraying. The color range in this set lives up to the rainbow name—each spool holds its dye evenly from start to finish.
