I wanted the boys to have matching comforters but that was not in the budget. So, I decided to mix the colors in with throw pillows to tie them together instead.
I started with the basic pillow, which I did in the gray color of my other boy's comforter. I used a pillowcase I already had to figure out the pattern. Then I added the smaller pillows for accents. The red pillow is from my 10 minute envelope pillow cover tutorial. There was only 3/4 yard of the Transformer fabric so I cut a crop out of it, and made the back gray, using the same tutorial, with some adjustments.
