Writing journal. Any kind that works for you.

Laptop so that you can type your writing and print.

White drawing paper [I have found that just about anything works. We will be scanning drawings and embedding with your writing.

Photos that you may choose to use to illustrate your writing.

Drawing pencils and pens. [Again, I find any old pencils work and any old black pens. It's up to you how "fancy" you want your supplies to be.]
