The first one I knitted was the Carlisle Cardigan. I used Cloudborn Highland Roving in Ecru, and I also held a strand of Madeline Tosh chunky yarn in the colorway Cosmic Wonder Dust. It adds some cute multi-colored speckles. And I added in a few streaks of hot pink to brighten it up even more.
That roving is really nice! It's super cushy, it doesn't pill while knitting, and it doesn't fall apart. It's not scratchy at all. It is quite affordable compared to other super chunky yarns, and they have 28 colors.
I actually knit this one on the wrong sized needles. I had ordered size 19 circulars through Amazon.com and when they arrived, I dove right in. As the sweater grew, I felt very crowded on the needles and checked the length. There was a sticker over the label, and after peeling it off, I saw that they were the recommended length, but I discovered that I had received and knitted with size 17. Visually comparing to the next sweater I knitted, using size 19 needles, the stitches are quite a bit smaller (I also used a different brand of super chunky yarn). But I like the way it fits, so I won't re-knit it or anything.
The pattern recommends using 24" circular needles, but I suggest using longer ones. It makes it a lot easier to work with the thick fabric (you can use the magic loop method around the neck and until the body is large enough around to use the whole length of the cord).
Once you get started, you might get hooked, like I did. I have made a few Good Day, Night sweaters so far and I have one more in mind. They come together so quickly, don't need much fitting at all, and I love the way they look. It is really easy to customize them, and to mix and match the elements of different patterns.
The only problem is they don't fit very well under my coats. Maybe I should look into sewing a coat with big, loose sleeves...
