This is a piece of raw silk that I pleated and stitched two years ago. I dyed it this Monday. The fabric measures 15 x 34 inches. I used the finger pleat method, gathering up folds of fabric with my fingers then using a running stitch and a very long needle to hold each group of pleats in place.
To the left is the pleated fabric after it was soaked for a couple days to wet it out; on the right after steaming and drying out a bit, just before I took out the stitches.
