I posted a few months ago about a baby blanket I made for a friend. I used the same pattern to make a blanket for my son, due November 15th. Since I knew the gender, I went with a mix of yellow, brown, blue and green.
Here is the pattern:
Cast on 5 sts.
Row 1: Knit
Row 2: K3, yo, K2- 6 sts.
Row 3: K3, yo, K3- 7sts
Row 4: K3, yo, K to end of row.
Repeat row 4 until you have the blanket size you want.
Next (decrease) row: K2, yo, K2tog, K to end of row.
Rep last row until 5 sts. remain. Bind off.
Weave in ends.
The only problem I ran into was that the blanket is a bit diamond shaped instead of square, and I'm not sure how it happened! I do know that the baby won't care, so it is what it is!
