HUmmmm... well I can't really think of any slogans .... but I know that my big sis and I made our shirts together. We chose really cool purple leopard fabric (its' fuzzy too !! it's great) and got black shirts with 3/4 sleeves at target and went back to her place, had lunch and cute letters out of the fabric and put that iron stuff on... I know you said you didn't want to do letters, but I really thought it was fun doing that and no real cute slogans come to mind at moment. Plus choosing the fabric together and everything was bonding time.
