Learn how to create the copper coin used in this tutorial: copper bracelet and fish leather skin.

Step 1 :
Start by drawing in the felt the shape you want to give the piece of copper, here rounded pieces of + or - 4 cm in diameter. Cut out the parts and degrease them with alcohol or soapy water and then dry them.

Attention all operations are dangerous, sharp, irritating to the eyes and skin,
it is best to do this in a ventilated room and put on protective gear (gloves, mask,
glasses).

2nd step :
Pour a little ammonia into an airtight container and then a piece of absorbent paper, deposit the copper pieces, pour the coarse salt, deposit a new piece of absorbent paper and over a stream of ammonia ( watch out for fumes ). Close the container and let it rest for several days. (The duration depends on the desired result, the more you leave it, the more the effect will be pronounced.) Be careful when you open the lid of the container to see the effect on the copper parts, the chemical fumes of ammonia are very irritating.

Step 3:
Once the desired effect is obtained, wash the parts with clean water and dry them. They will appear matte, you will remain to varnish. To do this, apply a thin layer of spray polish, let it dry and that's it, you just have to choose the ones you prefer for your creations!
