Hey! Well my Mallard ducks are getting bigger and bigger and I need a pin to put them in. But I don't know how much it would for a big pin. Also, if you decide to build one, what kind of wire and other materials should I use? It may be cheaper to just build one. My mother is wanting to use about half my graduation money to buy a pin with it. But I don't want to spend all of it, because I would like to use some of that money to buy other important things with. Well thank you!
