cut away and not tear away is great for this project too as it is firm enough to be handled the stablizer as used to stiffen collars and cuffs.
If you use a stable cotton that's washable and then use washable markers you could wash the colors out and color them again. A reusable coloring book!

A coloring book I recently saw recommended embroidery on a non-fusible stabilizer. (Pellon)
I would chose a good stable cotton fabric. That way it could be washed if needed. H&*
