My first thought was the Seahawks colors too. When I was a little girl my Grandmother made me a blue and green plaid dress of those lovely jewel colors. I loved it! I am collecting fat quarters to make a solid color 1000 pyramids quilt. I just have to get up the nerve to cut the fabric! Any time we step out of our usual it can be scary but we just have to take that first step. He'll love it because you made it for him!
