Here's a link to a bunch of textile mediums.

She said you could use any of the paint mediums.
She did a demo on 3 different ways to use the Inktense.
1) was just coloring with the pencil.
2) use the fabric medium and your brush at the pencil tip to get colors.
3) using a paper plate or freezer paper scribble back and forth with the pencil. Add a bit of the paint medium and mix the two together. I liked this one the best.
There are bunches of YouTube videos on this.
