Give your friend a scary makeover... tell them it's turning out great, but make it look scary and ugly!! That would be a good surprise.
Invent a board game... make it very interesting. You will spend so much time making it perfect, so it will give you something fun to do and fun to play all night long!!
Make a website!! Go to freeservers.com and make a FREE website. It's a lot of fun!!
Give your friends an extreme makeover... put all of your effort into it, especially if you like to do people's hair. If your friends like how you did thier hair, maybe they will let you do it more often!!
