Here's a great Art Attack, that involves no window and no glass at all - but it's very easy to make.

You will need:
  • thin card or thick paper
  • sticky back plastic
  • scissors
  • pencil
  • black acrylic paint
  • poster paint
  • washing up liquid
  • paintbrushes
First take a nice big piece of thin white card or thick paper. Use a pencil or a pen to draw a picture or design. Make it quite simple and bold. Draw the picture in fairly simple sections, like a stained glass window.

It's very important to make all the sections in your picture touch another section.
When you're happy with your design, cut a piece of sticky back plastic a couple of centimetres bigger than your picture all the way around, and carefully peel off the backing.
Simply place your picture, picture side down into the plastic.

If you have any bits hanging over the side, just fold them over and back.
Turn it over to have a sticky back plastic covered picture.
Next, you need to put some black acrylic paint in a bottle with a long nozzle.
Squeeze the paint very carefully over all the lines on your picture.

Do it slowly and carefully, to form fluent lines. Try to make all the lines of equal thickness.
When you've covered all your lines on the picture, leave it somewhere flat overnight to dry.

The acrylic paint lines will dry solid, and stick out from the picture, to look like real lead.
To colour your picture in, you need to mix two parts of poster paint to one part of washing up liquid. This will allow the paint will stick to the shiny plastic.
Mix whatever colours you need, and then you're ready to paint them on, one section at a time on your picture. You get a really good translucent effect. The light shines through the paint.

The good thing about this technique is that if you make a mistake, you can just wipe it off.
Do the whole picture in exactly the same way. When you've finished, you'll have something that looks like this - a glass window picture. And you can do whatever design you like. Just remember to join up all the sections of your design.

Try it yourself!
