Girls Birthday Party Supplies

hi im having a 12 year old birthday party with 4 girls (including me) next Saturday-and im the host. really, its not a birthday party, but its a sleepover. a lot of my friends, including me, absolutely love crafts. so then i decided we can all do one or two crafts during the day, whenever we all think the time is right. us being 12 we can make our own party decisions, plus my mom doesnt want to spend more than $10 on the so called party. i have 2 questions: the first one is that 2 of my friends go to my school. we all know each other and they both know each. but the other problem is that my very old friend (we knew each other for awhile) moved to Solon (like 3 communities away from where i live) a year ago. both of my other 2 friends don’t know her at all. What would be one idea we can do so that i can introduce her to them? my second question is what craft can we make for the party? help i need ideas! i only have a little time left to get supplies!
