I made some dolls very similar to this, years ago...I achieved the skin tones by tea dying PINK fabric. It worked great. I had one of these dolls as a toddler. My gramma made it for me...I used it for the pattern. I made high waisted dresses and nighties for them and the skirt of the dress was patchwork with a 2-3" sashing on the bottom. I just strip pieced 2 fabrics then cut the sewin strips and sewed it again...made a nice piece of fabric for the skirt...
My dolls were only about 18" long.
