B & T
Sew a dragonfly button on to the hat using matching cotton.
Have a look here for the buttons
Take a length of black wool and untwist it, so you can work with a single strand. The wool I used had 3 strands all twisted together.
Using this wool, work a running stitch from under the dragonfly, create a loop-the-loop pattern and then continue the running stitch around the back to the edge of the knitting. Fasten this end off.
Finally, oversew the row ends and turn inside out.
