Crewel embroidery is done with wool. In this case, it is a mix of wool and embroidery floss. My mother started this picture when I was a child. She died when I was 14 and I kept her work in progress for almost 20 years, all the time intending to finish it. I finally picked it up as a project to do in the evening when my brain was fried from nursing school. It was wonderful to finally finish it.
Pattern: Something from Dimensions in the 1980's...they don't make it anymore.
