5 7/8″ by 10 7/8″ this unique ruler cuts squares that will make perfect Half-Square-Triangles without any trimming.
Please allow 5-7 working days for delivery.
Ruler will have extra markings denoting the 3/8″ sizes when you get it.
Simply align a straightened fabric edge with the measurement you want your squares to be and cut, then turn the fabric 90 degrees and cut again.
Place two squares right sides together and use a pencil to draw a line diagonally corner to corner.
Sew 1/4″ either side of the drawn line using a 1/4″ foot.
Cut along the drawn line.
Press the HSTs open and marvel at how they are already the right size and don’t need to be trimmed!
