DIY Project: Kitchen Tiles

I have long wanted to try my hand at tiling my kitchen over the stove and sink, but I was always scared to do so.  I wish I had plunged in sooner.  Armed with a $30 credit from Home Depot, I picked out tile squares and the grout and matting the salesman directed me to.  For $51, here is what I was able to accomplish.

Here is my ugly backsplash above the stove:  a white metal sheet.

Here is what I was able to do in about an hour:

And, at the end of two hours:  this---I had bought 6 12x12 tile squares and had enough left over to do this 
ugly, white wall behind the sink.

I still have matting and grout left if I want to tile something else.
