Good morning, I'm up early and thought I would design a new corner shelf.  Everything is based on 12" squares.  It would use Kreg pocket screws to put together.  Hope you enjoy the design.

Check out our Sketchup animation of the design.  Subscribe to our YouTube channel for other information.

Post Edit:  I've had many questions on how to hang the shelf and how to assembly.  First for the hanging question, I would recommend to keyhole slot on the back of the two top pieces.   You can purchase a keyhole router bit at most hardware supply store.

Second question is the assembly.  A few years ago, I purchased a simple Kreg R3 jig (https://www.kregtool.com/store/c13/kreg-jigsreg/p169/kreg-jigreg-r3/).  For DIY woodworkers or hobbyist, this tool is a must for you.  I had never built furniture until I discovered Kreg tools.

It has been a cold spring in Kentucky.  I haven't had time or energy to get into the shop to work.  Hopefully, I'll get into the shop soon to make this couch table.  I've been trying to learn to use SketchUp to design some new projects.
