What Our Customers Say About Us

Bottom line--absolutely top performer, especially in the bobbin. It sews much thinner than it measures-not sure if I said that correctly.  This shell binding treatment is a vintage treatment that requires a thin thread for the finishing.  I had to use a heavier thread because the binding was made from a fabric I hand dyed.  Hand dyes are a different kind of beast and can quickly turn a borderline badly behaving thread into a monster.  Bottom line was a perfect choice because it is super strong but appears thinner than its stated weight and sewed through the heavy hand dye like it as air.
