It adds a greater array of built-in stitches – 294 in total, including decorative, utility, and alphabet options – and 10 memory slots for saving frequently used stitches. Added features also include a thread cutter button and manual upper thread tension control. Both models feature a pop-up reference guide and screen for easier stitch selection and dual LED lamps for superior illumination of the sewing area. Clearly targeted toward sewing enthusiasts, the NX-450 is several times more expensive than Brother's more basic and compact entry-level models, which offer a fraction of the built-in stitches and generally less advanced functionality.
