Okay, try these on for size mentally:
Carl's work is gorgeous and very inventive! I've played with this technique some, having developed a love for tucked ribs on my Passap and then translating them to the Brother machines, but in addition, Kathleen Kinder has some wonderful ones in her ribber books. However, for most of those, I had to draw/punch/input patterns. Carl has pulled these off with Stitch World classic tuck stitches!
