The clothes from the patterns for Kit, Chloe and Louise from Wee Wonderfuls (
www.weewonderfuls.com) fit 12-13 inch waldorf dolls well.. Some of the clothes for her Olive and Archie dolls fit them as well. Her doll patterns are pretty awesome too.
Also, Joys Waldorf dolls has a booklet you can buy with clothes that fit 13-16 inch Waldorf dolls.
I really enjoy making smaller waldorf dolls--13 inches or so, and have had a hard time finding patterns for them...there are SO many patterns for 18 inch dolls, it's unbelievable!
