9" Seam Guide Tool
This small and easy to use ruler makes sewing and cutting half square triangles super quick! The back of the ruler is coated with Creative Grids' non-slip material to prevent shifting while making your blocks.
To use the ruler: Just layer two squares right sides together, place the ruler diagonally across them and trace out the center and outer lines. Sew on the outer lines and cut on the center line and your blocks are done!
