I took a class from David Taylor. We used different metallic threads to practice. Everyone's favorite hands down was Superior Glitter. Use a size 90/14 Organ needle and low tension. Following his instruction not one person had broke or frayed thread or messed up bobbin stitches which was amazing considering every brand and age of machine was in class. The main thing was needle size, type and even brand of needles for each one of the metallic threads per machine. The guy knows his thread and needles.
He recommended the Thread Director to use on all machines for any flat thread or at least a thread stand.
