Paper cutting can make beautiful repeatable shapes. I used some red and white paper and an asymmetric tree design to make a striking handmade Christmas card.

Fold your paper in half, then in half again, and then again. Press down each fold with a ruler to make sure it is neat.
Unfold and then refold in a concertina - this is known as an accordion fold.
Draw the asymmetric tree design that will repeat along your paper. You can do this with a ruler, use a template, or simply sketch it free-hand.
Cut out your design with scissors or a craft knife. Depending on the thickness of the paper you may find it easier to use scissors. If quite thick then use a craft knife and go through a couple of layers at a time.
