These were the quickest easiest projects I have ever made. You literally knit a rectangle. The orange one I cast on 10 stitches and knit in garter stitch until it was big enough to fit her head. I then knit another garter stitch rectangle for the bow. After stitching them together I simply wrapped some yarn around the two to give the bow shape.
The mustard yellow one I did a bit different. Because the orange one was quite stretchy and Imogen kept pulling on it I decided to make this one in stockinette. I didn't want the edges to roll but so I did three rows of 2x2 rib on each side. This time I cast on a heap of stitches to what I thought would be big enough to get around her head. Then I did 3 rows of rib, 6 rows stockinette and another 3 rows rib and cast off. Simple! I then attached a flower I made ages with a pattern I can't seem to find at the moment. Unfortunately, my thinking was wrong and Imogen keeps pulling these off her head too. Oh well, at least they are cute for the 5 minutes she wears them!
