sorry about there being no pics i couldn't find the connector cord for my cell phone so i used Google images for pics, but anyway steampunk is when you take something 21st century and mod it, paint it, and add stuff to make it look as if it was made in the Victorian era or older. Like the stuff from the movies stardust or sky captain and the world of tomorrow.
Step 1: Materials
Step 2: Making it
this requires 89%imagination, 5% power tools, 6%materials. you could steampunk clothes, old toys, etc. i usually steampunk my Nerf guns or something but it's up to you
