A KFP2TOG or knit front purl 2 together is rather simple: knit through the front stitch, but leave it on your needle, then purl the next two stitches together. I've included a short video tutorial if you're a visual learner (I am 100%!).
This technique is used in the supple rib pattern of our Little Pebble Earwarmers pattern. What makes is supple? The act of working the stitch twice creates this tiny little bump. More pronounced than a standard purl stitch or seed stitch, almost like a little pebble. Give it a go and let us know what you think!
