These origami hearts make a great Valentine's day project.
You won't need any special materials or equipment just a sheet of paper and lots of patience. They are quite easy to make but the patience is important as there are a lot of steps.
The size of the heart will depend on how big your piece of paper is. A good starting point is to take an A4 piece of paper and cut it to make a square.
The folds create a stand for the heart as well so they will stand up on their own.
