The Brother LS-2125 sewing machine is perfect for basic sewing. It has 10 built-in stitches, a four-step buttonholer, a reverse sewing lever and 25 stitch functions. You can disassemble parts of your sewing machine to clean it or perform routine maintenance, such as changing the belt. Check with a sewing machine repair technician prior to disassembling it on your own, since this will void the 25-year limited warranty.
