The Singer Fashion Mate 3337 has many more functions than its predecessor, the 3333. 3337 sewing machines offer 29 stitches, including a 1-step buttonhole, stretch, overedge, hem, scalloped stitches and the ability to adjust the zigzag width and length of most other stitches. The styling of the machine is very seductive, soothing to the eye and smooth to the touch. A subtle downward curve at the front ensures that the material glides easily in the direction of the upcoming stitch. The 7-point feed system ensures a precise and even feed that keeps the fabric exactly where it should be. Like the 3333, it is a perfect sewing machine. The LED lighting illuminates the sewing area and the built-in automatic needle threader makes it easy to thread the needle eye. The horizontal spool pin also accommodates larger spools of thread up to 1000 metres, and threading the upper section is very simple: just follow the numbered threading grooves. Inserting the bobbin is even faster thanks to the bobbin thread setter. It works while the bobbin is being threaded and cuts off the excess thread so that you can start sewing immediately without having to make the first stitch by hand to bring the bobbin thread up.
