diamond stitch baby blanket

I used this diamond crochet stitch diagram to create the main body of the blanket. 3 balls of 50g baby soft green yarn (you can just make out the telling stripes that show I didn’t pay enough attention to dye lots!) then added stripes down one side in pink, blue, dark green, white, dark green and finally blue. The final row is a polka dot edging stitch I read somewhere, half forgot and then made up again until it looked right:

*sc next 4 stitches, chain 4, 10 sc into 3rd chain from hook* repeat to end of row
