Dip your pen in an ink jar, grab some sketching or painting paper, and start to work. When the tip of your pen begins to wear out, soften, or split, just cut away the soft bit and create a new tip on the same stick. You'll eventually have a collection of pens made from one original piece of wood. Here's how: Start with a straight piece of wood about 1/4" thick. Use a pencil to draw around a container to trace its shape. Then use a drill with a screwdriver bit to make several 1/4"-deep holes all over the surface of the wood. Next, pour rubber cement into each hole. Let the cement dry for several hours or overnight. When it's dry, scrape off the wood inside the contour line of the cup. Now take your pen tip and insert it into one of the holes. If you want, you can also add a small amount of rubber cement to the tip of the pen to glue it in place. Repeat this process with other pieces of wood and the head of your pen will be complete! A note on quality: Rubber cement is available in a wide variety of colors. So if you want to customize your pen further, just choose some that match with your paper or wood color.
