1. Four plastic drinking straws. If you can't find any straws, you could use wooden skewers or even two pipecleaners joined together.
2. Some sticky tape (the kind that you can't see, such as Sellotape, or 'invisible tape' is best).
3. A few sheets of drawing paper or card. The bigger your mobile is, the more card you'll need!
4. A pair of scissors and some paper glue.
6. Some coloured pencils and pens, or paints and paintbrushes. Acrylic or poster paints are best, but you can use watercolour paints.
7. A needle and thread.
