The Bottom Line by Superior Threads - This thread has a shiny appearance and is virtually lint free. It can be thin and lightweight, yet strong. Due to its smooth surface, it works well with metallic threads and heavy cotton threads. The smoothness of the filament poly thread does not snag or grab the top thread. If you've had trouble using metallics or heavy cotton threads, smooth bobbin thread may solve some problems.
Why is starch is my friend? Need to tame bias edges? Looking for the easiest stabilizer for stitching or just because you like to work with washed fabric with some stiffness. I prefer to use concentrated liquid starch, purchased at a big box store. A heavy solution of 50% water to 50% starch. Spraying the starch to warm fabric, makes the fabric firm faster. Need more body? Dip the fabric in straight starch and place in the dryer. Maximum stiffness? Dip fabric in straight starch and hang to dry!
