While I can't hazard a guess as to the age of the fabrics, the other items you mentioned (
dressmaker's tracing paper, a large envelope with design transfers) would lead me to believe at least the notions are from 1950's to late 1960's. The design patterns you mentioned are probably for hand
embroidery
- most often used on pillow cases.
I remember the dressmaker's tracing paper well. We used it to mark the location of bustline darts.......
