Had to go up to hook sizes to a G in order to get the gauge correct. Used a magic circle to start each one rather than ch 6 and join. Also did a standing double crochet at the start of round 3, and finished off adhered round 4 with an invisible join. This is my first time doing a join-as-you go method, as I don’t tend to do a lot of motif work, so I’ve definitely made a few mistakes but I don’t think there noticeable and I think I’ve finally got the hang of it now! Making this as a Christmas present for my Frozen-obsessed 3 year old :)

Update:
Didn’t finish in time for Christmas but it’s finally done! After somehow misplacing two skeins of the blue yarn and reordering some of the last skeins that were for sale in England (the yarn is discontinued!), just to find the different dye lot was really noticeable (ugh!), I found an angel on Ravelry who had the exact dye lot I needed and traded with me!! I was able to finish the blanket soon after, although it took me months to get around to blocking the edging months. I’m so happy that I was able to finish it after all the craziness! And my daughter loves it :)
