A lampshade should calm you, and help direct light too. That's why a birch bark lampshade is perfect for the nature lover. Bring the outsides to you, and boost productivity! this is a really easy project, but I'd only recommend to those with LED bulbs to avoid fire hazard.
Step 1: Shade
A piece of birch bark that is think and has holes will be perfect and add some interest. I'd only recommend around 3-5 layers of paper, in order to give a warm glow. You want to wrap around the bulb, using the amp head as a guide, and glue it with wood glue or epoxy at the seam.
Step 2: Light It Up!
Enjoy you natural looking lamp. As you can see, the birch interior reflects light well, and directs the light down to the desk very well, as a regular shape would. Good luck with your lamp!
