Last year we ran some “in house” tests on the Aurifil nylon monofilament with great success.
Naturally, a quilted piece of fabric is not usually pressed with high heat, but we do press applique units as we work, and monofilament is often used for machine applique, so it was important to check out the thread to see if it broke down in any way.
We were delighted to find that it stood up to pressing with a hot iron without any change to the feel of the thread. It also worked well when stitching at high speed in straight lines, and with ziggy zaggy changes of direction.
So you can imagine how pleased I was to read Laura’s blog about her successful testing of the Aurifil Monofilament …. pop over and read her funny descriptions of how cruelly she treated the thread and how well-behaved it was in response to the abuse.
Aurifil’s monofilament is a very fine thread ( I describe it as hair fine) that can be snapped between your fingers. I’ve used the ‘snap” test ever since I read about it, years ago, in “Heirloom Machine Quilting” by Harriet Hargraves.
She recommended using the test to judge if a monofilament should be used on a quilt …. if the thread didn’t snap she said it was too thick/strong for the quilt.
