I must say that I become a big fan of Star trek, but I am not maniac. But at he end I really want to have that signs =D
First you will need patterns. Uyou can find them overhead.
Then knead your clay and place the pattern.
Cut it out.
Add some pins and bake it.
After baking let it cool.
Than use your nail polish or acrylic colour and paint it.
And ta dÃ¡, youÂ´ve got the Star trek Signs/Communicators.
