Mélange Blanket Square 5: Catrine Square

Our fifth square pattern is the Catrine Square by KT and the Squid. You can find Katy online at Etsy | Facebook | Instagram | Pinterest | Ravelry | YouTube
You can see Katy’s version below. She used one color in King Cole Fashion Aran yarn.

I am using King Cole Big Value Aran (available through your local yarn shop or online at LoveCrafts or Wool Warehouse UK) and my Denise US Size J-10/6 mm crochet hook for my blanket. This makes it easier to keep consistent gauge across all my squares.
For my version of the Catrine Square, I used Berry for Rounds 1-2, Nougat for Rounds 3-4, and Ocean for Rounds 5-7. I changed colors in the slip stitch at the end of the round so I could follow the pattern easily. My square was closer to 5.5″ (14 cm) after Round 7, so I joined Nougat with a slip stitch to the stitch after a chain-2 space. To keep the stitch count the same, I worked 1 single crochet into each single crochet in Round 7, and (chain 2, skip chain-2 space) in each corner. I finished by joining with a slip stitch to the first single crochet. I lightly spray blocked the square but it wasn’t absolutely necessary. (If you’re new to blocking, check out Blocking Basics for Crocheters and Knitters.)
I found this pattern straightforward and easy to follow. I did make an oopsie – I made Round 6 in the back loop only as well as Round 7. It changes the texture a bit but I like how it turned out. There are several special stitches for this pattern. If you’re new to the front post double crochet, you can find my tutorial here, and if you’re new to the dc2tog decrease, you can find my tutorial here. Katy also has a video tutorial to go along with the written pattern.
