Paulina at Pretty Pink Posh posted these adorable Button Trees on her blog:
She took a styrofoam cone and used the pearl end straight pins to secure the buttons to the cone. After finishing them, she put them on candle holders for pedestals. She used the Bubble Gum and Lime buttons from DeNami available here: http://denamidesign.com/cart.php?m=product_list&c=118
You can also create the same look using a styrofoam ball and making into a Button ball ornament.
