I am a beginning knitter. I love to watch Knitty Gritty, and they have often mentioned that a "make 1 increase" is the least noticeable type of increase, so I want to learn how to do it. I understand that you pick up the bar in between the stitches and put it on the needle. My question is this: do you then knit it, or do you just slip it on and knit it in the next row or round? Thanks in advance!
