Baby Boy Cards

I've spent Wednesday evening in my scrap room making cards.  I had no particular occasion in mind.  I was in the mode for card making after helping my best friend make invites for her baby girl's first bday, she's the Miss Kayley Marie that I recently posted pics of:)   I LOVE to make cards.  I am hoping to get a booth at the craft fair this November to sell cards and pre-made layouts.  I made these baby boy cards, but now I want to add something to the big empty space on the right side.  ANY suggestions???
