Any specific brands are just my own recommendations. You are always welcome to use what you already have. 
1. Drawing paper (or multimedia paper). At least 5 pieces but more is great. The size of paper will  determine the size of your sketchbook. So if you choose 6in x 9in paper, your sketchbook will be half that size. 
2. Scissors.
3. Either a bone folder or a spoon (We’ll use this to press creases while folding).
4. String for binding. This can be embroidery thread, yarn, ribbon, really anything. 
5. An embroidery needle (can use other needles IF the string you choose is small enough.)
6 .Something for decorating the cover: paint, markers, pencils, etc. Whatever you like. 
7. A small cup of water 
8. Elmer’s glue (liquid not a stick) OR Mod Podge 
9. Pencil and ruler
10. An old paintbrush (we’ll be using it to spread glue)
