Lay your door mat on a table or workbench and use the masking tape to make different size triangles. Spread them out across the mat in a pattern or randomly.
Once your triangles are all taped up, you’re ready to start painting the tree tops. Colour in all your triangles with the green craft paint. When it’s dry, you can peel off the tape.
Now use the brown paint to create your tree trunks under each tree. You don’t need tape for this, just line them up in the middle of your triangle and paint a square.
All you need to do now is let the paint dry and there you have it, your very own festive door mat.
