Three-String Box Guitar

We'll kick things off with a Skype session with maker and author Kathy Ceceri (

What you'll get in your "guitar kit"

  • 6-8 screw eyes (for tying the strings and tuning)
  • 1 Drawer Pull (for bridge)
  • Srings (three sizes) made of fishing line
  • 3' piece of pine for the guitar neck
  • Misc hardware for attaching the bridge and neck to your box

You need to provide the box for the body of your guitar

Ways to customize your guitar:

  • Choose your box (your guitar box as art)
    • Lasercut
    • Paint
    • Create Stickers 
  • Finish the neck
  • Decide how you want to play it
    • Slide
    • Frets
  • Decide how you want to tune it
