Here's a great idea for a party invite with a difference! You can also use the idea for secret messages and, if you're feeling romatic, valentines! The invite looks quite normal on one side... ...but when it's turned over, a hidden message awaits! Folding in all the corners reveals the first part of the hidden message. The next part is revealed by folding in the corners once again. And the final part of the message is revealed in just the same way, by folding in the corners once again. The invite is very easy to make - all you need is an ordinary A4 piece of paper. Start by folding one corner to the opposite edge, like this. Make a crease. Do exactly the same for the opposite corner, making sure that the edges are nice and level. Then fold in the remaining flap and make another crease. Open the whole thing out and cut off the oblong flap that you can see here. This leaves a square piece of paper, the centre of which is marked by where the creases cross. Fold in the corners and draw or write on your first piece of information, like this. Fold in the corners again, and write your next piece of information... ...and repeat once more for the last piece of information. And if you turn it over, you can decorate the back, too! When unfolded, your friends won't be able to tell what the message says - it just looks a complete mess! The only problem with the invite is that the creases give the solution away. And if you want to use the technique to make party invites, it'll take ages to make lots of them! So this is where technology comes in. Just photocopy your message, or scan it into your computer and print out as many as you need. This will give you beautifully crease-free copies. You can give the technique a try by printing off this Finger Tips version of the four fold invite. Finally, remember that if you use the technique to make invites, you will need to tell your intended guests how to work out the message - otherwise no-one will come!
