Meribeth, Its hard to tell on my monitor, but they do look a bit bright for the period. Not having ever seen the original quilt "in person", it seems in my mind to be a bit drab in color. To me the book and the software show it as such. It would be hard to say how bright it originally was though.
Of course, looking at the BabyJane that I've made..I believe that you can do it an any colors you happen to like! :wink: Are you planning to do a Baby or have you already? Are you planning more of a "replica"?
