DD & her friends like to have a craft to do at parties. The 12 - 14 yr parties included things like start a scrapbook (they brought photos & I picked up paper, stickers & small albums at the Dollar Tree), bead pins (on those tiny brass safety pins), "beady buddies", necklaces made with hemp & beads, painted boxes and then filled with potpourri & at one party they made "mini food" (idea was in the American Girl magazine). The mom had to be in the room for using the oven with the last one, but only for a short time.
They also like "free form" time when the do each other's hair & nails - girly stuff.
This group likes "chick flicks" - I have to be careful because there are a couple who are not permitted to watch scary movies...and then a few others who can't watch certain PG-13 movies.
They love Disney's Scene-It, Dance Dance Revolution & other board games.
They love running around outside playing flashlight tag and they think it's really cool if I do a treasure hunt. That's one that takes work because their favorite way to do it is they play in 2s or 3s & each group has a different set of clues. First one done gets something "extra" but the "treasure" is just whatever "favor" we get.
