An automatic needle threader is also built in. Apart from this and a red finish with details of the stitching patterns etched on it, this is very similar to the Singer 1507WC in terms of features and build. Automatic 4-step buttonhole functionality allows for fast and secure button fastening, and a Class 15 bobbin enables large spools to be used that don't need frequent replacing. A free arm design allows the use of heavier materials, and a heavy duty metal frame avoids skipped stitches. This machine comes with a number of accessories, including a seam ripper, spool caps, and foot pedal.
