Andrew on this website (see link below) writes a very comprehensive article on how to make money making and selling pin badges.

He doesn't unfortunately, point to our website (we would be pleased if he did!), and I assume that is because the article was written from a North American resident point of view.

This doesn't invalidate the article in any way, because he does make a very good argument for badge making and selling, and even includes discussing the cost of production and selling prices.

Well worth a read!
