I used these free downloadable flower templates from the Purl Bee and some felted white wool fabric to make my flowers. I hand stitched my flowers in place with embroidery thread and added a little accent stitching as well. Really, a very simple embellishment and I managed to do all of the hand stitching in an evening. It's kind of a felt version of my favorite way to embellish a cardigan.
I love the little loopy flowers- now I'm trying to figure out what else I could use those for.
