So I was sitting on the floor doing one project or another and my b/f comes into the room and asks if I could use these metal circle things that were apparently the tops and bottoms of those consontrated juice cans. (His hobby is makeing wine and sometimes uses those. It's great) And I had them sitting in my craft bin of doom and got stuck with the idea that they would be great for the tribal head band and new fringe belt I want to make. Also does anyone know how to make them into half domes? I know it can be done to bottle caps just not sure how.
