30cm quilter's rule
This special patchwork 30 cm quick quarter ruler will allow you to make two-coloured patchwork squares with the necessary margins for sewing and cutting. This ruler allows you to draw 6.35 mm (1/4") seam margins on either side of your design line. The ruler allows you to make triangles without forgetting the seam allowance.
Ideal for making multiple half-quarter and square triangle blocks and flying goose blocks. It is also an excellent tool for making squares.
Usage guidelines: Align the centre of the ruler with the edge of your design, Trace along the edge of the ruler to obtain the 1/4" seam allowance on each side. The sliding part (black) allows, once blocked, repeated cutting of the same strip width
