Colourful felt

In London I fell in love with a colourful rug at Anthropologie. It was made of hundreds of little balls of felt, and just looked so pretty and comfortable - I would have loved to pack it in my suitcase!
And today, on Pickles, what do I find? A beautiful Christmas wreath made with the same 'ingredients'! I need to learn how to make colourful felt balls: I want a wreath and/or a rug like that too!
