Hereís a great way of using strips to make a sort of two-in-one swap picture.

You will need:
  • A3 sized thick black paper or thin card
  • white paper
  • white pencil
  • ruler
  • scissors
  • cardboard box card
Take a piece of A3 black paper or thin card.
Draw a ruler width strip along the top and the bottom with a white pencil.
Place the ruler down so that it lines up with the left hand side edge, and draw another ruler width down the card in between the top and bottom line. Move the ruler along, so that it lines up with the line youíve just drawn, and do another.

Repeat all the way across the paper.

When you get to the end youíll notice that thereís a slimmer strip. Cut along the edge of this slimmer strip...
...and youíll have something that looks like this.
Cut out alternate strips.

The strips with scribbles on are the ones that you should cut out.
When youíve cut everything out, youíll have something that looks like this - a set of bars.
Now cut out a piece of cardboard box card - the same size as the bars - and lie the bars on top of the card.
Get some tape, about the same length as the card, and stick it across the bottom like this.

It doesnít matter if itís slightly shorter. It mustn't be longer, however!

The idea is to put half of it on the bottom, and then wrap the other half around the back.
Do the same for the top, and when youíve done it, youíll have something that looks like this.
You now need to slip a piece of thick A3 white paper inside.

You may have to lift the bars up to do so.

Push the paper in so that the edge of the paper lines up with the left of the frame.

Now youíre ready to design your picture. It's a good idea to make it simple so that you can tell what it is through the bars.
When youíve done that, move the A3 white paper to the right, and the picture disappears behind the bars.

Now you can draw your second image on the blank paper thatís showing.

Itís a good idea to do opposites.
Colour in, and there you have it - a swap picture!

You could do other designs too. How about a caterpillar that turns into a butterfly, or ice cream that melts, or a little kitten that turns into a ferocious tiger?

Try it yourself!
