For my 11th birthday party, I decided to have a SPA party! For invitations, I bought four tubes of bath salts, and some plastic bottles (find at a local pharmacy, CVS, rite aid, etc). Fill each bottle up with some bath salt, and slip in your invitation rolled up. For a little more you could tie a ribbon around the bottle. A good number of people to invite is about 7.   When everyone would arrive, set up a large area (basement, family room,) as the Salon". Invite a neighbor or an Aunt to help with it. My mom was the facialist and the massuse. My neighbor was the mani/pedicurist. Have them wear all black and nametags. Some good names are Monique Brittany Alicia and Valerie. Have the girls take turns getting the things done. You could have some snacks or a movie playing as they wait.  Next we went up for cake and presents. A way to determine which present is opened first is to do hot potatoe with a nail polish to see who it lands on. A good snack is fruit smoothies or cookies.  The challenges were BLIND MAKEOVER and SPRAY AND SNIFF.  Hope you enjoy!! :-D"
