Here is what you need:
Metal stamping letters/numbers set, Fimo polymer clay, acrylic paint, flat wooden sticks, ceramic tiles or glass, cookie cutters, rolling pin, embossing tool or fat needle, paper plate, paintbrush and a cloth.
Take a piece of polymer clay and soften it while kneading.
Put the flat wooden sticks on the ceramic tile (makes it easier to transfer to the oven) and roll with the rolling pin over the clay so that it's nice, flat and even.
When you rolled out a piece, lift it up carefully and transfer it to another tile so you can roll out more little clay slabs.
Punch with your cookie cutters, figures out of the polymer clay slab.
Before you stat using your letter stamp set, wipe it off with a soft cloth. The stamps are a bit oily to make sure they don't start to rust.
Before you start stamping, try your stamp on a sample of Polymer clay.
This way you know how hard you have to press the stamp to get result and it will also be good to see if you're not holding the stamp upside down.
Hold the metal stamp tool as straight as possible and press lightly into the clay.

Take your embossing tool or needle to punch a hole in the clay.
Carefully take the piece of clay off the ceramic tile and punch with your embossing tool or needle on the backside of the clay so that the hole can be used.
Preheat your oven to 110°C or read the instructions on the packaging of the polymer clay you are using.
Put the ceramic tiles with the clay pieces in the oven for 30 minutes
and let it cool down afterwards. It's ready to use when they feel cold.
Put some acrylic paint on a paper plate and paint the sides and front of the clay.
Let it dry for a while.
When it's dry, rub it with a damp cloth so that most of the paint will come off again.
The harder you rub, the more paint will come off.
Here is another example with gold acrylic paint. Paint it.
Rub the paint away with a damp cloth.
In case you have a hard time getting the thin thread through the little hole, here's a tiny trick that makes it super easy...
Cut a small piece of metal wire.
Fold the metal thread in half and put the thread in between.
Stick the metal thread through the little hole of the clay.
