I recently joined the United Federation of Doll Clubs (UFDC) as a member-at-large. UFDC has been kind enough to let me post PDF's of past Doll Reader articles focusing on Izannah Walker on this site. You can find these and other articles in the list in the sidebar.
UFDC also publishes an excellent magazine called Doll News, a magazine well worth reading. When you join UFDC, you receive the magazine as part of your membership. UFDC has other resources as well. One example is the wonderful Izannah Walker Study Set by Linda Edward, which a kind reader of this site sent to me. It is a slideshow of Izannah Walker dolls in CD format narrated by Linda Edward, who wrote Cloth Dolls Ancient to Modern. I learned some interesting things about Izannah Walker dolls from this study set. For example, I had assumed cotton was the stuffing in the dolls, but apparently Izannah used a variety of stuffing materials such as bran or sea grass as well as cotton. Like doll makers of today, she used what was plentiful at the time.
In becoming a UFDC member, you can join a local UFDC doll club and have full voting rights OR you can join as a member-at-large, which is great if you can't fit another meeting in your life.
