My, your desk really is full of things!

Which is why you totally need a katamari to get everything together.  This organizer not only holds pencils and pens, but also sports magnetic ends to hold paperclips, pins or binder clips.

And if you'd rather an edible katamari...

Step 2: Form and Bake Katamari

You want a hollow clay ball...I'll describe how I made one, but there is probably a simpler way.
  • Mix and pour plaster in a frame (a wood or cardboard box works)
  • Set plastic ball half way into plaster
  • Once plaster has set, remove ball
  • Roll out clay in a 1/4" sheet
  • Fit and press clay into mold
  • Remove excess clay from around the mold
  • Carefully remove the half circle of clay and place on baking sheet
  • Repeat for second half
Bake katamari halves at 275oF for 15 minutes

Step 3: Bake and Glue Together

Sand the ends of both halves and glue them firmly together

Note: The picture shows holes already created in the top piece.  I added those thinking it would be easier at this stage, however, it is actually more efficient to drill holes after the katamari is fully constructed.

Step 4: Add Color

If you want a more colorful katamari, roll out a thin sheet of colored clay and wrap around ball. 

Bake an additional 15 minutes.

Step 5: Magnetic Katamari Ends

A tablespoon can be used to make more uniform ends...
  • Choose four colors of clay
  • Form into four balls of increasing size
  • Line tablespoon with a thin piece of plastic (i used a grocery bag) so you can remove the entire piece at the end
  • Place three smallest balls into spoon
  • Set in magnet and smoosh down
  • Place last ball of clay (the largest) in spoon and press down.
  • Remove the whole piece by pulling out the plastic
  • Set aside and repeat

This is so cute!

Any way to make this without clay? :)

Hmm...perhaps you could put holes in a large styrofoam ball and use smaller styrofoam balls cut in half for the ends. It may not be as stable, unless you have weighty enough office supplies. Then the item you attach can be made of anything!
Great idea!

I think I'll try it.
