Beautiful pattern! I’m making this for my sister who has stage 4 cancer, so I’m using cotton. Two of my yarns are fingering, but the other two are sport. Also cotton is less stretchy. For these reasons, I cast on 120 stitches with US1.5’s. I did k1p1 ribbing for an inch and a half. For every new color, I knit a row before beginning the kp ribbing. This kept the colors even. I just did 5 pattern repeats instead of 6, and it worked perfectly. Did I mention that this is a gorgeous pattern?
