I use that thread to handsew down my binding. It is also really convenient to carry with me when I take handwork to a get together. I put them in a baggie with several needles on a piece of folded fabric and a small pair of scissors to carry with my quilt so I don't lose them. Quite frankly I only use several thread colors to piece--white, cream, tan or gray and occasionally black. Since my Pfaff tells me when the bobbin is almost empty I don't mind using the those bobbins. My Janome does not have that feature. Boy do I hate to realize I've been merrily buzzing along without thread.
