A pencil is a good tool if you are going to use it for writing a list, especially if you are working with colored pencils. Ending2: [step] Anything that won't go away are great. [title] Find a nice colour suitable for your cell phone. Ending3: [step] A pencil that you can use for outside writing will also be handy for plotting the names of items on the list and making entries.
