I used this free pattern: http://kellsbubble.blogspot.com.au/2011/10/tea-time-doily-beret.html
Here are some images of the progress!
Here is the beginning of the petals.
Flower motif finished, beginning on the bulk of the hat.
The day I finished it I wore it out with a friend to the Tesselaar Tulip Festival
Originally I really struggled with making the hat, I was used to simple toy patterns so using a variety of different stitches was a bit confusing. But I succeeded and have already made another hat for a friend! A blog post for that is coming up =)
