This is a wonderful Christmas tree, which is very easy to cut out. And the heart on it is that one. But there is an "ear" on the template and not even one.
The Christmas tree is made of two sheets of colored paper glued together. After cutting it can be left as it is, and it can be glued on cardboard (as here). Oh, and the template is designed for A4 paper for borderless printing (it's for the whole sheet).
