Rainbow blanket

Our toddler is long for her age and is rapidly getting too long for her baby blankets. Thus I've started knitting a "big girl blanket" for her, using Kauni effect yarn (colourway EQ). I'm not usually very fond of multi coloured yarns, but this yarn is different - the long colour shifts makes stripes rather than chaos. I'm knitting it on the diagonal as I don't know if I have enough yarn. I'll probably need an additional skein as I want the blanket to measure approximately 1,5 m x 1,5 m.
