How to make a paper Christmas tree

Just made a paper Christmas tree, a little wonky but ok.
I made it by drawing 2 identical Christmas trees 109cm in height
on quite thick card 300gsm, then cut them out.
With black ink I then drew small circles in the shape
of paper chains on both sides. The last step was to cut from the
top of one tree 95cm down the middle and measure 95cm from
the bottom of the 2nd tree and cut through the middle
with scissors or a bladed knife.
To assemble slip the tree which has the cut at the bottom over
the top of the other tree. Ta dah!
I'm going to have a go at making one twice the size!
