Thank you!

Looking at two articles I'm not sure it'd count as mosaic crochet since I only worked into the last round, never* the round before that. I think it's just a colour change?

Sometimes I carried the unused thread all the way, sometimes I crocheted it in for the first stitch or two of using a new colour and then left it to grab later (this makes it so there's free thread going through the middle). This applies to the stripes on the tail, too - it's just starting and ending the second colour in different places, no working into rows already worked into.

/*aside from whatever that was once or twice when there was a big enough hole ;')
