My sister and I had a steamer trunk full of paper dolls that we played with for hours growing up. Over the years, each doll developed her own history and personality that we built upon every time we played. To this day, there are still private jokes she and I have tied to that collection of dolls. It is one of my fondest sisterly memories.
Collecting the paperdolls became something of a hobby even into our preteen and early teenage years. We were always looking for more good quality dolls. Had the internet been around back then we might have printed out hundreds of dolls for free!
Here is a list of good-quality, printable paper dolls available for free on the internet. I have tried to include only sets where the dolls are dressed modestly. If you notice any problems with this in the links, let me know so I can edit this post.
Marilee's Paperdolls. Probably THE best site for printable paperdolls. Literally hundreds of dolls, plus printable doll house with furniture
Karen's Whimsy - vintage paper dolls from various eras
http://www.ushsdolls.com/- United States historical characters paperdolls
My America paper dolls- simple designs based on the Dear America book series
http://www.gallimauphry.com/PD/gateway3.html Adult paper dolls from a variety of historical periods. Also included are some sets from great pieces of literature. Some of the sets contain some immodest figures; so parents might not want to let their children have free reign here. I included the link despite this fact because it really seems to be a useful resource. Could be great for homeschooling.
