I've been looking into patterns I could use for a baby blanket for my little niece/nephew, and I really like this one below:
My sister-in-law is keen too, and my brother seemed as interested as you could reasonably expect from a bloke...!
The pattern is here.
They are planning to find out the sex of the baby, so I'm going to wait until then and choose colours depending on what they are having! I'm impatient, I want to start now!!!
