I’m trying to use a pattern for a bag, courtesy of a friend. The pattern instructs me to “cut two rectangles, 14 by 16 inches from main fabric”. I have sewn for a while now, but never without a pattern.
I tried using a yardstick to mark the lines on the fabric, but it kept being inaccurate and changing the position.
How do I accurately cut a rectangular shape from fabric without a pattern to trace?
