Swiss dot type crisp cotton or cotton blend fabric, 60s vintage... with flocked pin dots! This is a medium weight, not terribly sheer. Nice and crisp, looks easy to work with.
It's a ladylike pale pink, dots are an ivory shade not pure white. Measures 45" wide x 2 yards +.
There's a spot or stain on this which I haven't attempted to remove, since the fabric has never been laundered. Please see the last photo.
