First time - Increase for Left Handers

Good afternoon, I am knitting a baby sweater for my niece. I have a woman at work who is teaching me, but today is Saturday so I cannot ask. How do I increase 1 stitch (left handed) at the end of a row that ends with a purl stitch? :rollseyes:


I don’t know if it’s different for lefties, but you can purl into the front and back of the last stitch.
