HELLO ALL, 
      I HAVE A QUESTION ABOUT SOME STITCHING, ON MOST CLOTHES(STORE BOUGHT) ON THE HEMS,,, IS THIS A HEM STITCH OR COVER STITCH ,,,,OR ARE THOSE THE SAME BASICALLY. ON THE INSIDE OF THE HEM IS  STITCHED AND CLOSED, AND ON THE VISIBLE SIDE IS 2 STRAIGHT LINED STITCHES. DO YOU HAVE TO HAVE A REGULAR SEWING MACHINE OR A SPECIAL DOUBLE NEEDLE SEWING MACHINE. I HAVE BEEN SEWING A WHILE WITH AN OK SEWING MACHINE BUT I'M KIND OF TIRED OF CLOSING AND THEN GOING BACK FOR THE SINGLE STITCH. AND I'M PROBABLY TAKING THE LONGEST WAY AROUND TO DO MY SEWING, I WOULD THINK THINGS COULD BE MORE TIME SAVING. THANKS
