Hi and Happy Birthday to your DD!
My DD turned 5 in February and she had a Disney Princess Party. We did lots of crafts. One that would work for you if you can find Tinkerbell fabric:
I made hats from frabric and poster board and Tulle (the netting for a veil off the top.) They were regular cone style hats (like any cardboard party hat would be with elastic to keep them on) with the veil coming off the top. I traced the shape onto posterboard, cut it out and then attached the fabric. There was no sewing, I used adhesive to stick it all together and a glue gun for the elastic underneath. I had the hats all complete for the party, but to add something for the girls to do, I bought colored gems from Oriental Trading. They came in hearts, ovals etc, and we used pink, purple and the clear ones. The girls got to add the gems with glue to give their hats a personal look. The girls loved it because it was a hat that they could play dress up in at home. I got a lot of compliments regarding how beautiful the hats were from the parents as well. It didn't cost much, I actually found the Princess Fabric at
Walmart!!! All together for 10 hats I paid about $25, but they were worth it.
Also we played a Snow White game, similar to hot potato, but with a "poison apple" This could easily be modified to Tinkerbell, just use a small plush doll of her or something like that. We used Disney Princess music, but I am sure any fairy type music would work for you. I cannot remember if Tinkerbell has a song!
We also colored "Belle Bookmarks" which I got from the Disney website. It was the actual size of a bookmark, I am sure they would have some Tinkerbell images as well. I bought yarn and punched a hole and...voila! an instant bookmark.
I also love planning kids bithdays, can you tell? I get more excited than the kids.
Also, a dress up trunk is a great thing to have. Get some fairy wings, tinkerbell accessories etc.
Have Fun!!!!
