Pattern: "Granny's More Complex Star" by Jacqui Goulbourn.
This was a fun and kind of challenging square to crochet. The only issue I had was with round 5 where it says to "join yarn with an sc to any 5th dc of a triangle point. hdc, dc..." I wasn't sure where was supposed to put the stitches until I read ahead since the pattern doesn't say. It does turn out that each stitch of that round goes in the next stitch of the previous round.
