#Knitting_Tutorial - "Knit into the front and back of a stitch to increase. The difference here is that there's no bump because you don't actually knit into the back, but just slip the stitch off the needles in addition to having knit into the front. Clear, detailed explanation at the site. So brilliant!" comment via #KnittingGuru
No Bump KFB: Instead of knitting into the front and back of the stitch, knit into the front of the stitch, don't remove it, go in as if you're going to knit into the back and slip it off the left needle onto the right. You eliminate the purl bump.
