Pole dyed cotton sheeting, with good definition of the wrapping cord on the cloth. As a bonus, you also get lovely, dyed cords to play with.
The lower piece is cotton organdy, which is actually a more vivid green than this photo depicts. It stays curiously crunchy when dry, despite vigorous washing and rinsing . I might give this to one of my Morley mates who is a milliner and who uses a lot of organdy.
This is my 199th post – amazing.
