I'm working on my first C2C blanket for a cousin's new baby. Diagonal color changes are so easy with this technique! The baby's name is Lydia, and I think she'll like these sweet pink stripes.
I had to read a couple tutorials to get the idea, but after the first few rows it became second nature. If you're interested in trying it, Craftsy has a tutorial with a lot of photos here. After you become proficient at it, you can make some neat-looking graphic blankets.
The way squares alternate in horizontal and vertical direction gives C2C an interesting texture. I like running my hands across the blanket as I work. The drape is more structured than most work, but the added thickness makes it a good fit for a play blanket. I used some Caron Simply Soft gifted to me by my boyfriend's brother, who moved on from crochet (he's a man of many hobbies). On a whim, I decided on a rectangular shape this time.
