This hat from the "Inspired by Steam" collection is designed to support the idea of steampunk for daily usage.
I like when virtual things or characters from books become true in real life.
Materials used: genuine leather, copper plates, copper wire, painted aluminum plates, gears, rivets, temperature gauge.
Cotton surface is naturally aged under the Sun influence.
Update: I've started next hat decorating, and creating tutorial in parallel. Related details are in "Tutorials" gallery and my Journal entries.
