Wooden Christmas tree with colour-changing lights

Step 3 Cut out the tree outline

Now use your saw to cut out the tree outline. Try not to cut off your fingers as this will make the later steps more tricky.

Remember to wear a face-mask while cutting MDF or you'll be coughing and wheezing all through the holiday season.

When you've finished cutting, use a piece of sandpaper to sand any rough edges smooth.
