I don't know what a Stickie is but here are more ideas -- I did these when Gina, my AGoT alterego, was earning her American Girl Historian certificate.
For Molly: she interviewed my mother (her grandmother) about her experiences as a young navy wife in WWII. Then she typed up all her notes and made a doll-sized notebook, illustrated with copies of B&W photos of my mother & her family & Dad during the war. (I took photos to my local fast printer & had them reduced to 33% of their original size. I did that with all my paper doll crafts.) This was a great bonding experience with my mother.
For Felicity: Several AG's got together for "an evening in Felicity's parlor", all dressed in Felicity's period costumes. They played checkers and cards by candlelight, then some of them played musical instruments (lute, piano, flute & violin) while others danced the minuet. Then they had tea from a silver tea service and Felicity-style cakes and cookies. At the end, one doll told a story while all the others listened by candlelight.
To return the invitation, Gina had a Christmas party for the same group, during which they made "pomander" ornaments. These were small satin-covered foam balls decorated with ribbons, pins and sequins (instead of an orange stuck with cloves)in colors that matched each doll's outfit. They had punch in Sam's lemonade glasses (cherry juice w/ginger ale) and flaming Christmas trees for dessert. My cat helped to clean the dishes because the Christmas trees were circles of cake with a dab of ice cream, covered by whipped cream, with a birthday candle lit on top. He liked the whipped cream!
For Addy (would also be nice for Kaya): Morgan Snowfeather, my pre-Kaya Native AG, taught a class in making beaded necklaces after the dolls had an outdoor potluck picnic. (That's what you do when you've made lots of FIMO food for a while.) Gina made FIMO alphabet cookies to spell out each of her friend's names. Other dolls each brought their favorite food. Every doll made two necklaces to take home afterwards.
For Samantha: Gina studied about French Impressionist painting by reading and visiting our local art museum. Then she did an impressionistic watercolor painting of a potted flower. Finally she delivered a lecture to her classmates about her favorite Impressionist artists. Her lecture was illustrated by doll-sized reproductions cut from the back of a Monet calendar (the small pictures on the back cover) and matted by mounting them on construction paper.
For Kirsten: We had a spectacular Midsummer Solstice celebration with a dozen dolls dancing around a Maypole, wearing long gowns and flower crowns. My neighbors loved it! Gina also embroidered the corner of a hanky with her initials, mine and my mother's. Then she painted wooden spoons (Dove bars have nice wide wooden sticks for a handle) in red and decorated them with Scandinavian designs.
For Josefina: Several dolls got together to make ramilletes. They cut out pretty shapes from old Christmas cards, then glued photographs of themselves and their friends to the center and hung them with cords of embroidery thread. (Doll sized ornaments are fun to make! If you take a group photo, you can cut it up and get several centers for the "flowers".)
We haven't done activities for Kit or Kaya yet but for Kaya, we'll definitely have a powwow!
