It’s also handy for machine quilting when it’s hard to choose a color, for example in quilts with both dark and light patches. Some quilters love using it for things like quilting in the ditch so stitches that are off track don’t show.
Monofilament thread typically comes in transparent smoke and clear colors. Since it’s shiny, like thin fishing line, the smoke is best against dark colors.
You can also choose between nylon and polyester. Many quilters prefer poly because nylon tends to stretch more and is more likely to tangle. Plus, some brands can yellow over time. However, others swear by it.
Monofilament thread can be a bit tricky to work with at first. You may need to adjust the tension, load the spool horizontally instead of vertically, change the stitch length or needle size, and more. Some quilters avoid using it in the bobbin, while others do just fine with it.
In other words, you may need to do some experimenting to find what works for you. The brand of thread can also make a difference, so give yourself time to try different things until you find the right combination.
