Well you make you a templet out of paper or card boardthat is 8inches
square an set it down an then place ruler down where your pattern ends
an cut a strip that is 8 inches wide.Then you use your ruler to measure
eight inches from edge an cut it.An then keep on an go clear across the material.If materialis 36inches wide an yuor material is folded you'll get two cuts each time with four around 4 inches left.Dont use the edge of materialcut it off about 1/4 inch off before you start cutting.OK
