Try this, Hold the ruler on the fabric with your left hand. Using your left hand will keep the fabric and ruler from wobbling. Using a fresh sharp blade, use your right hand to run the blade along the right edge of the ruler, cutting off a piece of fabric the exact size you want. It is just cutting, nothing fancy to holding the rotary cutter, just take it slow.
