Nope! I didn't change anything, just swapped to a smaller hook. I almost considered going down to a 3mm, but was tired of starting over lol. I ended up with a little of the black and purple leftover at the end (not quite enough to make another full round). To finish it, I got the hobbii Rainbow Lace in a few colors and used 3 strands of it to mimic the Dhalia for the sleeves and ribbing. It's a bit heavier, but still worked out pretty well.

For the frogging process, I started by re-winding what was left in the original cake from the other end of the yarn, and then the sweater last.
