I used an upholstery needle (curved like a "c") and twisted some floral wire into the eye.
I wanted the wreath form to have some bulk so I used straight pins and pinned on some batting all the way around the form.
I thought about some felt flowers, but the one I held up to it kind of disappeared against the pattern.
Awe. Now on to a new Christmas wreath. I probably should think about that before Christmas is over.
