My son Brandon celebrated his 1st Birthday in December and I decided to do it of Sesame Street, since he loves Elmo. I made the invitations on the computer, I got some graphics of Big Bird, Elmo and Cookie monster off of the Sesame Street website (the coloring pages) and I adjusted them on Paint and then transferred them to make an invitation from a Greeting Card software. My husband and I both have big families and we had about 150 guest (adults) and 45 children ages 1 through 13.  The party was in my backyard.  I rented a tent and about 9 tables, I had red, blue and yellow tablecloths and to each pole of the tent we tied red, yellow and blue balloons. At the entrance of the party I rented a wooden big bird (about 10 feet tall) and a wooden Elmo (about 10 feet tall) and they were each on the corner of a picked fence with an arch that said Happy Birthday.  I rented a tablecloth for the cake table that was hand painted and had all the Sesame Street Characters on them.  For Party Favors I made Baskets for each child the basket had a Sesame Street Book, M&M's, Bubbles and Sesame Street Stickers.  As Centerpieces I had a styrofoam and I wrapped about 12 lollipops(tootsie roll or blow pops) in red, yellow and Blue tissue (each lollipop looked like a flower) and put the lollipops in the styrofoam and in the middle of all the lollipops I put the Elmo centerpiece of Sesame Smiles. They looked really nice. First the ponies arrived they were there for an hour, then we had a Sesame Street Show, Elmo, Big Bird and Cookie Monster came and they danced with all the kids, they did the limbo the conga, they helped break the pinata (oh a gorgeous pinata with stuffed animals of all the characters) and of course sang happy birthday.  I also made Elmo necklaces for all the kids, I found plastic small Elmo at a local party store and I got red satin ribbon and made a necklace with Elmo, all the kids loved that (some parents tell me they wear it all the time),  also I rented another wooden Elmo that was about 4 feet high and it had a hole in the face so the kids could put their face in the hole and take a picture.   After we sang Happy Birthday, I rented an Ice Cream truck  and they arrived so needless to say all the kids ran to get ice-cream (so did the adults).   And that was Brandon's Big Bash! It was great!!!!
