I use their site all the time to create custom calendars and chore charts for my kids. Although I have never used them, I know they have a "greeting card" section too. My kids love that they can pick and choose the images on their stuff, and whether or not we print them in color or black/white. The latter lets them color the picture themselves.

I believe that flylady.net has a kid section.

I don't know of a site, but I've seen similar things at office supply stores and craft stores. What I've done myself is find clip art (google search) and used clear packing tape to 'laminate' the items (like starts, that I give out as rewards but they give them back at the end of the day).

Try www.dltk-kids.com. They have crafts, charts, calendars, coloring pages, bookmarks--you name it and they are free. No, I don't work for them but have used this site many times and have always been impressed with the variety and quality of the printouts.
