Thread Savy- Mono-filament Threads

Mono-filament threads are a whole other class. They are an embroidery thread of a sort.They are a war horse thread with specific purposes. But they do not really work for any classic dense embroidery.

Why?

Because they are so strong. In general, threads that are made of one particular thing are stronger than threads made of several substances twisted together. Metallic threads are always weaker than single fiber threads, because they're really not all of one piece. It's lurex, viscose, poly, and often a partridge and a pear tree. Metallics are not only a test tube baby. They are hybrids.Mono threads are one single substance that is stronger than the cotton threads of your fabric. Which means it can, if misused, cut through your surface fabric. So some caution and information is a real help here.

Early mono-filament nylon:
In the seventies, when we had the beginning of of knitted fabrics and sewing for knits, mono-filament came to the fore for lingerie and stretch knits. It was almost like a cord. It also melted easily with an iron.You could iron your garment and watch the seams separate. It was a heavier weight thread at around #20, which made it way too strong. It was wonderful for hanging sun catchers and that was it's very best use.Lots of the bad stories about mono-filament thread are in response to those original ones.This was the mono filament nylon they said could hurt your machine. It could. It came in giant cones. If you still have any of this left, use it for hanging pictures or make some mobiles. Please don't sew with it.

Mono-filament now:
We've come a long way.Because of the intense strength of these threads, it's recognized that they should be usually 40-70 weight (remember that larger numbers are thinner threads). They're perfectly safe for machines, both in the needle and bobbin.They also come in polyester and in nylon. The polyester ones are also available in colors.

If they aren't in colors, they'll come in clear and smoke. Clear is for white and pastel work. Smoke is for anything darker. Withing those formats, it really is invisible.

They shine as stippling threads. They work very well in both contemporary work and in traditional machine quilting looks. They are much safer for your surface fiber if they're done with a straight stitch.

You may be tempted to use the colored ones for zigzag embroidery. Don't. They're #70 which means they won't fill in well. And they will cut through your top fabric.

I do use mono-filament as an appliqué thread and for couching, with a zigzag stitch. But in both cases I never stitch densely. I stitch just enough to attach everything. Dense zigzag stitching with mono-filament will cut through your surface fabric, even now. But I haven't had one of the newer mono-filaments melt ever. They've licked that problem.

I also use them as a major part of bias application. If you check out my book, Quick and Easy Machine Binding Techniques, you'll see it used to sew down the top edge of bias tape. I'm not sewing those puppies by hand.

Wrapping it up
Mono-filament threads are brilliant for sewing things down invisibly, for stippling, and for straight stitching. They can be used zigzag, but with caution. And as always, garbage in, garbage out. You can't afford cheap threads.
