and fold them in half.
Cut a large U shape (so the straight part of the U is at the fold)
Unfold and make sure they look right.
Refold and hold in a heart shape to ensure you're happy with the shape. Trim a bit if needed.
While still folded and stacked together, cut two slits starting at straight edge running about 2/3 of the way up the U shape
To sort out how far up to cut, imagine your U shape is a square with a half circle on top. Cut up to where the half circle starts
Now it gets a bit complicated:
Take the red and "open" the top loop. Take the white and stick the first end down inside the top red loop.
Now (on the same end) open the white loop and stick the
second red loop partially through.
Stick the white end through the last red loop.
Keep weaving the loops together to form the heart shape
