Colorful Cups and Balls for Sorting -- Motor Development

My daughter is about to turn 3!!!  I am working on a few hand-made presents for her.  She loves color (what child doesn't!) and could use some more motor practice so I put together this little play set.  I ordered all the pieces separately and luckily, they fit together great!  All I did was paint them and I still need to put my wood rub on the cups. 

The little balls are 1/2" in diameter and the scoop is 3" long.  I got them all here but there are many different craft suppliers. 
Anyone have a favorite supplier?
