Soft, thin, transparent filament nylon in a beefed-up thickness and large spool for longarms (approx 10,000 yards per spool)
- feels soft - not like fishing line
- will not melt with a home iron - despite common mis-information
Use for quilting when you don't want the thread to show, when you are stitching on different color fabrics and don't want to have to match thread to each fabric (T-shirt quilts), or for stitchjing "in the ditch".
