One guess was the piece on the right with the text on it. This piece was hand-dyed and printed. It was first dyed green, but wasn't very inspiring. So last summer it got new life by being over-dyed with a teal color and color magnet. You can still see some of the original green in the photo below. The pattern was created by screen printing with a product called Color Magnet by Jacquard; after printing, it is allowed to dry. During dyeing, more dye is attracted to the color magnet creating a tone-on-tone effect.
