I know that many of you are already aware of this, but just in case, I must mention it yet again. (I already mentioned it on my Old & Good site). When you see the old brown gowns, quilts, and other brown textile items, they were usually originally lavender to purple.
Pictured here are some strips taken from a very old quilt. Note the lavender on the seams that never saw sunlight.
Just had to share.
