Button Crochets?

Over the weekend, I crocheted something a little different; and it's rather tiny too... a short break from my flower crochets. I felt that there is a need to develop something new and also to expand my crochet horizons.  Therefore, I came up with these circular crocheted pieces!! I like to call them 'Button Crochets'... looks like one! At the moment, they are still in loose pieces. I intend to attach them together to form an accessory piece; maybe a bracelet or a charm,

... still thinking, will post again on my finished piece.
