For my daughters 3rd birthday, she wanted a Princess party.  We started by renting a community center building just in case of rain, we made direction signs out of thin plastic sheeting in the shape of crowns and added a couple balloons to point the way to the center. The invitations were made using Disney's print creations with Cinderella and the prince dancing on the front, inside it stated "Princess Maddie requests your presence at her 3rd Birthday Ball!"  We took red fabric I found on sale at Wal-mart and made a "red carpet" runway on the sidewalk up to the building.  I bought the see through celophane wrapping paper from Easter in pink, purple, and blue to cover the glass windows and doors to give it a rainbow effect inside when the sun shown through.  We put the cake table at the front of the room with a big castle cake in the center, a plastic "silver" serving try with heart, star, and crown shaped finger sandwiches on one side, and a heart shaped bowl of chips on the other. We put a second table off to the side with other snacks and drinks.  I used pink tablecloth on the cake table and cut a paper purple tablecloth to lay over the pink with points to hang down sort of like a crown.  The other snack table had purple tablecloth, and the kids table had a baby blue table cloth.  In decorating, I put a balloon chandalier hanging from the center of the room, using pink, purple, and baby blue balloons.  From the chandalier, I hung the streamers (same colors) and sort of draped them over to the walls and taped them to the very top of the wall. I also had some balloons hanging from the ceiling on longer ribbon to have a dropped effect.  I then took white christmas lights and went across the ceiling in drapes along with a few of the streamers then hid the extension cord with white painters tape, and placed a huge princess poster over that.  At the back of the room we had an old chair painted gold and added a few of the plastic jewels from wal-mart, we put a tall plant on each side with white christmas lights and draped sparkly tulle in like you would christmas tinsel on a tree.  Behind the chair we had light pink wrapping paper with sparkly glitter to serve as a backdrop.  In the back corner of the room we had a large plastic washtub with water and three toy bathtub fish from wal-mart in purple, pink, and blue.  We hung a large poster of ariel behind the tub and had three different boxes of prizes colored to match each fish. The pink fish was small prizes like a pack of gum, sitcker, or plastic bracelet, princess pencil, etc. the purple fish was a little bigger prizes like jacks set, small bottle of childerns fingernail polish, etc. and the blue box was larger prizes like princess cup, coloring book, etc.  The children would be blindfolded and pick a fish, then pick a prize from that box. That assured that each child, no matter what age, could be a winner and get a prize. We also had the "kiss the frog" game, sort of like pin the tail on the donkey, girls wear lipstick and kiss a poster or drawing of a frog, whoever came closest to his lips won a sparkly magic wand. (also from wal-mart) When the children arrived, each was seated at a table that had homemade coloring books and crayons. The coloring books were made from disney's website coloring pages, and put together in clear plastic report covers.  That way, they were entertained while waiting for other guests, and they got to keep the coloring books. Each was also given an empty goody bag and a tiara to wear (oriental trading)  When all guests arrived, the girls were all lined up for face painting, after their face was painted, they were sent over to the "throne" and had their picture made with their tiara's on and a sparkly tulle drape around their shoulders.  (These pics would be later used as thank you cards!) After having pics made the girls would go to Ariel's "Whale of Fun" game. They could play till the prizes ran out or their empty goody bags were full!  Then last but not least the "kiss the frog" game.  After all the excitement, the birthday girl got to open her gifts and then cake and ice cream! After the party, I took the pics made on digital camera and used the Disney print creations cd-rom to make thank you cards with their pictures on the cover!  It was a big hit and they had a momento from the day they were all Princesses! I have to give credit to all the other people who have posted on this site, most of my inspiration came from several ideas combined that were posted on this site!  Thanks!
