font for posts on Spun theme

What is the font Carolyn uses for the Spun theme? I love this theme except for some elements. I hired someone to help me with those and he trashed the whole thing. Frustrated I hired someone else and they are also doing everything different. I want to use the lovely layout and font that Carolyn has designed. Is it possible to get the fond name so that my designer can perhaps give me what I want? Thanks for the help!
