You really can use any flower that you want to accent the hat. I used a carnation pattern that I found on allcrafts.net. There are a lot of other options there too. I liked the carnation because it stood off the hat and gave it a little more dimension.
As you can see, I have made a couple of these already. They are so much fun and so cute! I would love to see what color combinations you use and what flowers you decide to attach to your hats. Please post pictures when you are done. Since posting this pattern I have stopped posting on this blog and have struck out on my own. : ) I am now the writer of String With Style. You can find it HERE. Please follow that link and come over for new patterns that I have written. I hope all of the directions for the additional sizes are clear. Please let me know if you need any clarifications or if there are any errors. THANKS!!!
