The MC3500 gives you computerized Janome sewing with 50 pre-programmed stitches, including 4 different fully automatic buttonholes. The LCD display makes it easy to see which stitch you've chosen as well as the width, length, and thread tension. Create your own custom stitch settings that the MC3500 can "memorize," in combinations of up to 50 selections. A jam-proof magnetic, top-loading, full rotary hook system eliminates the need for a removable bobbin case. The hook cover plate opens at the touch of a button, and the extra needle penetration power of the Memory Craft 3500 lets you sew across fabric of any thickness without jamming. The extension table also detaches for free-arm sewing.
