I use my 1/4 inch foot with guide. I have one for everyone of my sewing machines. It makes a beautiful seam and it also makes sewing curved pieces so easy. I also went to e-Bay and bought acrylic guide. It has marks on the guide for a scant 1/4 inch, a regular 1/4 inch and other marks. It is really handy to have and it was only a few dollars.It is called a Clear 1/8 Laser Cut & Engraved Ezy Seam Helper. I bought so that I can use my Mom's treadle sewing machine. Her treadle is a straight stitch only machine, so I needed to know where 1/4 is and put a metal guide there so that I can sew accurately. I have no connection to the company that makes this item, I just found it useful. Good Luck!
