Finally done with this blanket! Only using one colour was a challenge and it did get boring after a white. I used two strands of aran weight yarn held together with a 15mm hook that I had to buy from Ebay.
My cousin requested a grey border so I used Stylecraft Aran weight yarn in silver and an 8mm hook.
I did my usual corner to corner pattern and just single crochet around the border. This crocheted up quickly due to using a giant hook and chunky yarn. I can’t wait to get back to my colourful blankets!
