I wouldn't do justice without giving credit to supportive quilt author Kyra E. Hicks. I guess she's been on the scene of many years.... and had certainly set an inspirational stage for persons like myself. Equally engaging is her book "Martha Ann's Quilt for Queen Victoria." I spent days learning about Liberia and its history - past and present.
