I also used one to bring a message across in a friendly manner.
I spotted some felt in my favorite craft supply shop (I really shouldn't go there too often). Loved the colours, so I spent some money, got home and started cutting out small pieces ending up with a doodle.
I made one, then another one, tweaked the design and thought of a way to be able to attach them to something. Then I made a couple more...hearing myself mumbling "OK, just one, with purple and orange. Oh, and one with green and ice blue, or...maybe hot pink and yellow..."
Then my husband came in asking me: "What are you making?"
He seemed a little disappointed when it didn't turn out to be a new car, a microscope or a digital camera. So his next comment was (imagine a somewhat UNSERIOUS tone of voice here): "...but what will you use it for?"
For husbands, obvious things like where to use small handmade felt flowers for, are often not so obvious. To give him an idea (he might want to learn...always leave that possibility open), I have put them on as a brooch, decorated a belt, used them for gift packaging, as a serviette holder, stuck them on a couple of leafless branches, used one to keep a scarf in place, all combined with some of my doublesided satin ribbon.
So - I think/hope/am pretty sure that answers the question. Of course these "millefleurs" can never compete with a new climbing set or gadgetty electronic stuff. But they are easier to handle, nicer to make and look prettier. If you ask me.
P.S.: I have a ton of them, so if you'd like one let me know. Just leave a comment with how you would put them to use and I'll pick the funniest/most original/best idea (in my completely subjective eyes) and send the "winner" one (let me know which colours you like in general and I'll start digging into my pile). Oh yes, I'll include a meter of matching doublesided satin ribbon as well!
