I made this:
Love it! First I made one large flower, did some outline stitching. Added a center to it, and bam, one flower down. Then I did the white flower, added some yellow stiching, and a yellow center, and bam, flower number two. Then I added a felt rosette (love those babies!). And finally, I used some triangular scraps of felt which I glued to the back of a large green button, and bam, flower number four. Add a few buttons here and there, backed it with old jeans, and used t-shirt strips for the straps! Easy peasy lemon squeezy!
And in case you're interested, this is where I found my inspiration.
