My daughter wanted a princess party the only draw back was that she has lots of BOY friends too so we had a Prince and Princess party. I printed the invitations on the computer with a castle in the back ground and wrote HEAR YE HEAR YE We are calling for a gathering of all prince and princesses to come gather in the royal celebration of Princess (name) 5th birthday. It will be hosted at Park Kingdom at 1:00 the 21st day of June in the year of 2001. RSVP Regrets only .We rolled them in scrolls and tied with ribbon and delivered them by hand. I made blue posterboard crowns for the boys (you can use a burger king crown for a pattern)and  swords. I made cardboard shields with foil on them and printed their name on the computer and glued to the front. For the princesses we made pink felt hats very easy with pink, purple and white curling ribbon and laces coming from the top of the cone and we made magic wands. they were just pink felt stars glued onto dowel rods with curling ribbon bows and lace bows tied on and glittered. REALLY CUTE!! We were at a park and we set the table with a pink flowered paper table cloth and pink plates. I made her a Barbie princess cake where the Barbie's dress is the cake. We picked wild flowers the day of the party and put them in vases on the table (which were actually empty plastic hug a jug containers with curling ribbon bows on them) I put just enough water to weigh them down but not enough if it got spilled it would make a big deal. We had picnic type food and we made an actual castle from appliance boxes...it was so easy. We sponged on grey paint to make it look like rocks/bricks all over and cut out windows and doors. There were two tall boxes: I also cut the jagged part along the top to make it look like a castle does. Then we took another box and made a usable draw bridge. We put flags on the castle that said park kingdom etc....and put a dungeon sign below one of the windows for fun. We played pass the poisonous apple and the kids got a candy necklace when they were out. We did a pinata. We had older siblings of the guests there to paint fingernails and "battle paint" on faces and body glitter available. We had all sorts of glittery baubles for them to glue onto their shields, crowns and princess hats. The girls got to take a vase of flowers, their hats, wands, pinata candy, fingernail polish, body glitter, rings and bracelets home with them. The boys got to take their swords, crowns, shields, pinata candy and squirting battle toys home with them. Oh and I dressed in an old silvery sparkle prom dress and said I was a fairy god mother.....oh the things we do for our children....The nice thing was we had several kids there over 20 because it was at the park in the summer and of course older siblings came too and they ranged from 2-9 and they really all had a blast. Oh for the thank you cards we took a picture of them all in front of the castle in their costumes and made copies. We made paper frames and wrote the thank you on the back...
