I used white linen for the gown which I dyed lavendar for the gown using the J. P. Ryan Pattern. I could not find any linen online that was the color I wanted, so I dyed it myself. They would have done this anyway, so I did. But yes its not a period dye, its rit dye, but hey it works. :)
here, it has diagrams and drawings of all kinds of garments form the period. When my sister and I and are friends and family went to Williamsburg for our graduation in 2010 we were also able to study many garments. We found the book on that trip as well.
My cap was made by the lovely Sarah Jane over at Romantic History. She was having a sale of many of her own garments she had made for living history and I jumped on the cap because I was running out of time before an even to make one actually. In the future I will probably make a second one to have one hand if I volunteer more at the farm.
