You'll need polymer clay, which can be purchased at a crafts supplies store like Michaels. You'll also need something to make the loops from. Myself, I prefer to use a headpin and poke it all the way through the charm.
The head of the headpin goes at the bottom. You can bake the pin in or use the pin to make a hole and pull the pin back out. Once the charm's been baked, make a loop above the charm at the top of the pin.
Yes, put the pin back in if you pulled it out for baking. You can get headpins at the same crafts supplies store where you buy your clay.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
