I always have lots of bottles laying around from the mass amounts that I drink. So I decided to make something useful out of one, a pencil holder.
Step 1: Materials
All you need is a plastic bottle, any knife that can cut through that bottle, and some pesky pens that are all over your desk.
Step 2: Cutting the Bottle
Here just cut the bottle at the height you want to have your pens at.
Step 3: Attach Pens
You are now finished so now just add some pens.
