DIY: Confetti rug

I first saw this DIY on a tablecloth on Oh Happy Day. But I decided to make a rug for my newly painted kitchen.  I chose the same blue color of the wall in another shade for the rug.  Here's what I did and how it turned out. 

Originally my intention was not to photograph this DIY, hence the lack of step by step photos, but since it turned out so great I decided to post the final result.
