Take a piece of paper or cardboard ( I used a page from my visual arts diary, it's 28cm x 35cm or 11" by 14")
Cut it in to 2
I forgot to take a photo before cutting it, but basically draw this design on to one of the pages and cut out the letters and the sides, but make sure you don't cut the horizontal lines.
Make sure you don't scratch the thing under the card, I put an old notebook under it
Here's what the back of the card looks like when folded
Paint the other piece of paper that you're gonna stick under it to hide the back
You can use any colour you want but I made it rainbow. You don't have to paint the whole thing because only part of it will show through.
Glue it on
Here's what it looks like when it's finished
Here's another one I made. Thanks for reading :)
