I have finished the baby blanket! I used Sublime Baby Cashmere Merino DK yarn and the pattern is from Sublime Little Hand Knit Book 600. It was a nice easy mindless project to knit, especially with my baby brain at the moment!
It varies slightly from the pattern, in that I’ve used 6 colours, not 4 and I’ve done mitred corners on the border.
Doing mitred corners was easy. I picked up stitches along the edge of the blanket and then increased into the first stitch on every subsequent row. I then mattress stitched the corners together.
