related to this, does any one know how to print on tan cardstock so that it would not copy well? I would like to sell the coloring kits inexpensively, but not if someone is just going to make their own copies. I'm going to do a test of some brown and yellow, and maybe pale blue ink. I want them to be visible enough to be a guide but actually not only discourage copying, but allow the creative person to do their own thing.

Do you have a photo or a link? I googled it, but only the wooden nesting dolls came up.

the idea is the same look as the wooden nesting dolls but in different mediums. There are lots of pillows and stuffed ornaments in the blogs.

I don't know much about what you are thinking of doing, but I do know that if you print your images on colored card stock, it will be harder to copy.
