Sewing Machine Seam Guide
Align your sewing machines’s needle simply and easily.
Place under machine foot with ruler along right edge of foot. Adjust needle so when needle is lowered, it goes through the hole for the seam size you want.
For vintage machines with a metal base – place needle through the hole for the seam size you want. Place a magnet along the edge of the ruler. The magnet will stick to the base and be your sewing guide.
