I'm a lefty--for writing and hand sewing But for cutting I listened to my teacher and cut right handed.. I use rotary cutter in BOTH talk about confusing. But I love, LOVE my Fiskars 24inch Rotary Ruler the cutter is attached to the ruler and can cut up to a 6 1/2 inch strip. No worry where your hand or fingers are blade can't slip You just push down to engage blade and slide. Material doesn't slid either has a "gripper" Can't recommend it enough I looked on You tube but didn't find anyone using one of these got mine at Walmart years ago. Didn't mean to write a book:):)
