There were about six or seven balls of the yarn left over from the purple jacket, so I looked around and found a pattern for a toddler.
This hooded jacket was so simple to do, just need to get a couple of buttons to be completely finished, and I still have more of the yarn to finish. I went through all my patterns and couldn't find a chunky pattern for a child, I shall have to see what I can find next time I go out, or else there may be some more of these in various sizes.
