Super-fine nylon monofilament thread
Smoke 1000m (1094 yd) spool

Monofilament Invisible Thread
Made in Italy, is made of nylon and available in two colors: smoke (for dark fabrics) and clear (for light fabrics).

Aurifil Invisible is great for machine quilting, machine appliqué, machine trapunto, stitch-in-the-ditch, curved crosshatching and scallop border, invisible hems and many other techniques.
It is smooth and shiny but not reflective.
It is the perfect choice, whenever the thread or the stitching line should camouflage or needs to be absolutely invisible.
Safe for High Speed Machines! Safe to Iron!
Art Quilters will love the camouflage effect, when couching becomes important.
The smoothness of the thread also allows its use in needle turn applique or when joining the parts of open seams, that need to be hand stitched to close.
While in many occasions you may want to stay “invisible” with your top thread

This 100%-nylon Italian-made thread for machine quilting and machine applique is a "zero thread breakage" product with a smooth, shiny (but not reflective) finish.
Used in hand & machine quilting and blind applique.

Adjust your tension. ( thread has a stretch)
You’ll probably find you need to reduce your top tension setting slightly to achieve a nice tension with invisible thread. Make yourself a practice piece to check your tension before working on your project.
Use a smaller needle.
Invisible thread is very thin. You should use a smaller needle. Try size 60/8 sharp/microtex needle when using invisible thread,
but will sometimes go up to a size 70/10 when free motion quilting
for a bit more strength to deal with the needle flex.
