Dell Keyboard (had 8 years)
I actually have three keyboards I've been saving to use in craft projects, but I've had them all for many years.
Since the keyboard consists of several parts (keys, interior stuffs, casing) it's all the materials I'll use for this challenge.
I have never found any really cool projects using keyboard keys (well, except this viper) so I'm going to see if I can improve upon this.
Each week, I'll select 2-3 items I've had 5+ years and use them in a project. And I'm going to document it online in order to trick myself into thinking that the nameless internet hordes care, and I must appease them.
