I have a girl and boy 2 yrs apart- so I have co-ed parties. To try to fit a birthday theme for both sexes I like to find movies with which to center a theme. Once I did a Peter Pan party. My girl dressed up as tinkerbell and my boy was a pirate. Guest were encouraged to come as any character. My eldest dressed as wendy and wore her pajamas.
We always start the party by kids making their own favor bags. I get free grocery brown sacks at Rayleys (with the handles). If they don't have handles I staple on ribbon handles ahead of time.
I print up a stack of theme free coloring sheets from the internet(in this case peter pan), and put them on a long table with markers , crayons, glue sticks. The kids decorate them and put their name on their bags.There is also crepe paper streamers in rolls on the table, they can use it to decorate the bag too, and to cover up and store printing on the bags. I like to have the crafts and games be the take home goodies. For this party we had a treasure hunt. We made 'crocodile creek' by stapling an ocean blue sheet of fabric into a corner, leaving room for hubby to squat behind. The kids each got a turn fishing at crocodile swamp and getting a crocodile squirt gun on thier line (with a clothespin on the end of the pole string). The last child (birthday kid)got also a paper clue on his pole...to walk the plank (boards put on bricks out in the yard)to the skull Island...an area decorated with my plastic skeleton from halloween...where the kids had to stomp on black balloons (cannon balls) to find the next clue inside one of them. That next clue lead them to another part of the yard,where they were to find the bucket filled with paper pirate hats (or a craft station to make them). Another stop had eye patches. Another stop had tinkerbell's fairy dust ( pixie stix - 5 of them wrapped in sparkly tulle). Another stop was the den, again 'crocodile creek" where they were to play hot "crock" potatoe. We stuffed a green sock (crocodile), with a kitchen timer.We had the movie soundtrack and played the song "never smile at a crocodile" in the background while they sat in a circle and passed him around. The last player left took the crock home and also read the next clue.(we gave each contestant a chocolate coin too). The final destination was a big basket we put in a hole in the yard. In the basket we placed the loot (gold coins inside brown lunch sacks, the tops cut ragged,and tied off with cord to look like loot bags. Each child had a name on a bag, there was "One Eye Jack" "Peg Leg Paul" and 'lindsey longbeard". Inside the sacks were gold choc coins, Hersheys 'treasure' candy, rolos, any candy wrapped in gold or silver foil. Plastic rings, etc.
So, at the end, their home made goodie bag was filled with their treasure hunt goodies and crafts they made along the way. Because we spent so much time preparing other things, we simply had pizza brought in. Because all the guests were dressed up,(including us) we had the cutest pics. many adults were talking like pirates. ARR! If was a lot of fun.
Another idea is a Mexican party with a taco bar. Borrow people's crocks pots. Have one with beans or chili. One with spicy hamburger. One with tortillas surrounded with foil. one with nacho 'liquid' cheese.
Put out a huge bowl of tortilla chips. sides of sour cream, salsa,lettuce, etc. make virgin strawberry magaritas for the kids. Pass out sombreros to take home for favors, and pin the tail on the burro. Beat up a pinata. Play Marty Robbins Cd's Use deep red, green, white , bright orange and yellow colors on cake and in streamers. Play The Three Cabaeros animated cartoon for the kids, or walt disney's Zorro for older kids? (I've never seen it.)
A picasso party could have the kids making artwork, paintings, clay figures, drawings, etc and having italian dinner -spagetties and such. favors could be decorating an apron (use sharpies instead of paint so they can use them as soon as they are decorated)a little metal bucket (find mini metal paint buckets at Orchard)with a nice big paintbrush, sets of paints, glue,rulers, a kneaded art eraser, colored pencils, fancy edge sissors and other supplies.
Once we had a Ratatoulle party. We did the 'make your own favot sack'. we played the movie sound track. Each child was given a chef hat (I attached grey mouse ears made out of felt) and we placed mouse wiskers and pink noses outlined in black on their faces with eyeliner. We cooked mini pizzas,(the kids made them on pita breads or mini pizza bobolies),we made leaning towers of piza with hard spagetti and mini marshmallows for the joints, They each cut up soft cooked carrots with plastic knifes, and dumped them into the pot of (already cooked)soup. (we ate soup, garlic bread, pizza, salad) They also made cookies. Going home, their goodie bags had their chef hats, their aprons, a wood spoon, a mini spatula, a mini rolling pin, some raw sugar cookie dough to use a home, and also I found a printable fun workbook online in a ratatoulle theme and made one for each of them.(they also have ratatoule cookbooks at amazon.com). We took a pic of all the mice together before they started cooking(o: and the finale was for the kids to watch the movie while the adults relaxed. If I spend a lot of money on favors i keep the guest list small. I found the spatulas and aprons at dollar tree and the paper chef hats at Boswells/pleasanton, mini rolling pins at Ross.
ps..the soundrack cd's can be given to the bday child- or given away as a door prize before everyone leaves- pick a name out of a hat.
