I found a tutorial for origami bows but it was is Korean. I thought I would a) give it a go and then b) try and explain the steps in English. I'm a complete origami novice and it took me a few tries to get it right so don't give up!
This is how the fold lines should look in order for it to fold into itself in the next step. You can see that the 4 corners coming off the center square are folded in "mountain folds" which means that they fold upwards like a mountain peak and the sides are folded in a "valley fold" so they crease inwards.
