Here's a really easy trick to put a border onto any of your drawings.
You will need:
|Find a picture that you'd like to put a border around.|
|You'll need a piece of paper that's exactly the same size as the paper the picture is on.|
|Fold the paper in half, as accurately as possible.|
|Place it in the middle, again as accurately as you can!|
|Draw around it in pencil, lightly at first.|
And there you have it!
Now you can go over it in pen and decorate the inside.
If you want a deeper border you can fold the paper in half again and draw around that in the middle.
Try it yourself!
