So I took 10 minutes and came up with a simple template dividing an A4 sheet of paper into 5 squares and 1 rectangle for the branches and trunk and coloured them into the corresponding colours, so that anyone with a printer can print out the template in colour or colour it in and fold it into Christmas tree for their desk or apartment. Perfect for any room.
The great thing about the A4 page is that it can be scaled up to A1 meaning you could in theory make a massive Christmas tree based on the template.
Step 1: Print and cut
Then cut it out very carefully.
