Adding studs is a great way to update and add a little detail to any clothes and accessories. I bought these triangular gold studs on ebay really cheaply, about £3 for 50. It was really easy and quick to do and I still have about 40 left so I'm going to have a lot of studded stuff!
Place the studs pointy side down on the fabric and push through.
Push down the points, I used scissors to do this. Keep adding as many studs as you like. I just did a few on each side but you could do a collar or make a pattern.
