You can use a plain piece of paper, coloured paper or origami paper [this option means colour is different on different sides= wings will be different colour to the heart]
The difficult part is folding the heart but once you got that, it is a nifty little accessory.
TIP:You can use different sized paper to get bigger or smaller versions as long as the paper is square.
Follow this video to make the heart with wings origami
pinch the centre of the wings only [behind the heart-do not pierce the heart] and pierce it with the safety pin [or with a sewing needle].Keep the safety pin in for the brooch. You can pierce two holes so that for the brooch the heart stays level.
you can also use this as a hair accessory. For this you can put a bobby pin in the hole and put it in your hair :D enjoy!
