In the 50’s and 60’s when I started needle work the dye issues with thread were resolved. So you could buy all the standard colors and not worry about the thread bleeding out. So long as you didn’t wash them in hot water. Of course you hear about the penny patterns that you would iron on, I am not sure they were a penny, we had bunches of them. I even have a special box with those patterns and finished pieces in the top of my closet.
You will hear of Redwork as a form of American embroidery but I have read that redwork came from Europe and was also called “Turkey work”. Of course we also hear that the only stitch was a Kensington stitch which is really an Outline stitch favored by the Kensington School for Girls in England. Whatever the history redwork gained popularity between 1855 and 1925 and has grown since. It has a rich history with crafters that I just don’t see ending. Sometimes there is something so elegant in the simple lines of redwork.
