From my personal collection of pieces by my great-grandmothers (you may have caught a glimpse in this recent post):
Some of it is embroidery but others must have names that I don't know. The tiny green woven knots floating in the openings on the pillowcase? The astounding intricacy in purple on another pillowcase? If you happen to know what the processes used to create these are called, please leave a comment and let me know.
