These are a great Christmas activity to do with kids - if they can hold a pen they are old enough to do it, you only need a few bits and pieces and they only take ten minutes.
Things you need:
A few white bottle tops
Some coloured permanent pens (I used Sharpies)
Ribbon (string would probably do)
Glue gun (sticky tape would probably do)
What to do:
Draw snowman faces on half the bottle tops and snowman body buttons on the other half
Use the glue (or sticky tape) to stick on the ribbon (or string)
