My eyes must be better in the morning. Look for a piece of heirloom light blue batiste. The imported 100% cotton stuff is pretty see through. It is expensive, but a true quality fabric. I made baptism gowns for twin granddaughters out of white batiste, and their slips were in pink and lilac. The colors showed gently through the white with a very nice effect. I think a light blue batiste would allow the stems to show through well, though you might need to go darker in the green.
