MasterPiece Cotton Thread

Lesson 108 from Superior University featured MasterPiece™, a 50-weight Egyptian-grown extra-long staple cotton thread. Designed specifically for piecing, it can also be used for appliqué, detail quilting, bobbin thread, and lacework. Our assignment was to make a pieced block and finish it as a hot pad. I wanted to test the thread for appliqué as well, so I added some patches to a traditional pinwheel block.

Originally, MasterPiece was a 2-ply thread. After reports of many newer-model machines causing it to break, Superior Threads decided to strengthen the thread by making it 3-ply. I was concerned that the thread would be heavy, and it is. Nevertheless, I was able to piece and appliqué successfully with this thread.

For many years now, Aurifil 50-weight 2-ply cotton Mako has been my preferred thread for piecing and appliqué. It never broke on my 13-year-old Bernina 170 but I haven’t tried it on my brand-new Baby Lock Crescendo. After completing this assignment, would I consider switching from Aurifil to MasterPiece? I’m afraid not.

There is one caveat. MasterPiece is available in sets of pre-wound bobbins called “Donuts” and I think this is a great option for hand appliqué. Although the spool and cones have been converted to 3-ply, the bobbins have remained as 2-ply. The smaller size and handy container make them portable and ideal for hand projects.

MasterPiece is a very smooth thread that claims to be virtually lint-free. I feel the same way about lint as I do about fusible web sticking to sewing machine needles. So what? Wipe it off. But a lot of lint can certainly affect our sewing machines, especially if we don’t clean them frequently. Owen’s Olivia has some fascinating photos of different threads under a microscope. Aurifil 50-weight cotton is the first image; there is also an image for “Superior 100% Egyptian Cotton” thread, but it doesn’t say if it is MasterPiece or whether it is 2- or 3-ply. You can definitely see the difference between all the different photos!
