Find Kardus

I am sure several of you who have been following for awhile remember Brodys sports nursery? Well we decided to do this little guys nursery the exact same way. I had all of the bedding/accessories and it was like new (Brody never used it)and my husband is obsessed with sports and insisted on another sports room and this was the cutest I could find even after looking for something new! I did get a new crib and dresser/changing table because I had sold Brodys and I found a great find on craigslist! I have a big chair and Ottoman in the light blue color that will be coming and I want to get a bookshelf. I also still need to add some things to the walls and his name! Where I need your help is... I want to get a big rug to go in here and I have no idea what color to go with? What would you all suggest? I would love to mix in stripes or plaid but would that be to much? Also, Ive thought either getting a Vinyl Decal of his name and or a quote or I have someone that could paint it? I need some help!! I am just not having a good vision this time around and although it is very similar I want it to be a bit different from Brodys nursery.
