I agree about the scarf idea. I was actually thinking the same thing. It is made with yarn doubled throughout, so that may be a little thick....
the pattern is as follows:
Size 10 needles
Cast on 23 stitches (remember, use two peices of yarn) work rows 1 through 4 of pattern stitch until piece measures desired length ~40inches for baby sized blanket 60inches for afghan, end on row 1. bind off stitches.
row 1: k3, *p2,k3, rep from * across row
row2: k3, *k1, yo, k1, k3, rep from * across row
row 3: k3, *p3(purl yo as a st), k3, rep from * across row
row 4 k3, * sl1, k2, psso (pass the sl st over the 2 k sts), k3, rep from * across row
Also, the afghan size has 7 pannels.....I think it is really up to you how many you use. I tried using this pattern without doubling the yarn, and it didn't really work well.
because it was a baby blanket, I decided to use simply soft yarn by caron. It is really silky and soft feeling, but it is still a worsted weight, not really thin, like some other baby yarns. So...in short, it was a worsted weight yarn.
it takes about 4 balls of yarn per color. The pattern calls for the yarn to be doubled, so you are knitting with two peices of yarn at once. Each panel is knit seperately, and then, once you are done, you simply use a yarn needle and one of the colors of yarn and use a batting stitch to stitch the panels together. It truly is one of the easiest blankets I've knit. If you have any other questions, feel free to ask.
