Confused over pattern, slip stitches etc.
Hi, I am knitting a blanket for my baby who is due in April, and have got a bit stuck. Was wondering if someone could please please explain really really simply how to do this bit:
slip 2 sts purlwise, knit into back of 2nd st on left-hand needle then knit first st in usual way, slipping both sts off neele together.
Really don't know where to start on how to do it, would be really grateful for any advice.
