YLI Invisible Thread Smoke
Length: 1371m / 1500 yds
Material: 100% Nylon
Invisible thread is used on the top (through the needle) normally with a thread such as a 50 weight or 60 weight cotton thread in the bobbin. We do not recommend using invisible thread in the bobbin. To keep the spool tidy we recomment thread nets.
Great for quilting where you do now want to see the stitches.
