With this Seam Guide Ruler you can set your stitches accurately on any sewing machine. With the free Magnetic Seam Guide you can easily keep that exact distance when sewing.

Is perfect piecing your thing? Do you want more accurate seams than your sewing machines needle plate markings are able to give? 

There are 16 little holes in the MadamSew Seam Guide Ruler which are made to insert a sewing machine needle. Use these holes to measure your seam allowances accurately from ⅛” to 2” and set your stitch on your sewing machine. The fluorescent green color of this seam gauge makes it highly visible against all fabrics.

You get an extra Magnetic Seam Guide with this ruler to make sure you keep that exact distance while sewing. You can just attach this little metal seam guide temporarily on most needle plates or metal sewing machines. The seam guide will not shift when you are sewing.

Note: For ¼ inch seams you will need to either place the magnetic seam guide before the presser foot, if you can on your machine, or move your needle all the way to the right, so the seam guide doesn’t get in the way of your presser foot.  For less than ¼ inch seams, use washi tape instead of the magnetic seam guide.
