My first babies were chaulky. I think I had too much paint, or did not bake long enough. It is not BB babies-- It’s just the method you are doing. Trust me, I could screw up all of them!
I have not baked one with hair again, but some say to put conditioner on the hair and wrap it in a cloth if you bake again.
I just kept doing more babies until I perfected the painting. I read everything on BB I could find. Sometimes the way someone words it, you have an “AH-HA” moment, and realize what you were doing wrong. For me, someone said the mixed paint should look like skim milk, and then I got the picture. Before, “thin” paint, did not “tell” me anything.
