2nd Birthday Invitation

How do I get a half fold Printable Birthday invitation that is free, because I need some invitations for this?
I am 11 1/2 years old,I will have my sleepover on this Friday.
My daughter loves printshop but whatever you have on your computer you can use. Take colored paper or even blank (not lined) 4x6or3x5 cards and use them as your base. Print off the info in some neat lettering smaller than the card on you computer and cut it out to glue on. You could put wrapping paper or colored pp behind it, you could even glue some curled ribbon out the top (place it between the card and glued on pp accents, use glitter or such if you have any- it would be cheap and fun and not take that long! Have Fun!
