Crochet Baby Blanket

I made this for my friend's baby. This was very easy to adapt the pattern for what I had available.
The original pattern called for rows of alternating colors, but I thought that this self-patterning yarn would look wonderful. For a sense of gauge, each sofa cushion is 58 cm wide. Also, my time to complete may be a bit off because I kept making mistakes so I had to tear it out and do it again several times. I imagine if you are experienced with crochet then this will only take a day or two.
