Okay I got this first part. It's easy, in fact. Adjust > Add/Remove Noise > Add > and enter what she said.Go to the top menubar and click Filter<Noise<Add Noise.
Add 10% of Noise, and make sure Uniform and Monochromatic are both checked.
This adds a cotton fabric effect...
I cannot seem to figure out the best way to achieve this. It really does work though. The image looks just like flannel!... but I will go one step further to get a soft fuzzy flannel effect.
Go to the top menubar and click Filter<Artistic<Rough Pastels.
Adjust the Stroke Length to 6, Stroke Detail to 4, Canvas Texture Scaling 100%, Relief 20, with Bottom Light.
I even considered a series of steps but realized that it likely will not work since stroke is so specific.
