Mezza mandolina is a variant of lacis. The difference between it and lacis is that mezza employs increases, decreases, different stitch lengths, dropped and added stitches, to create the decorative effect. Since I have not yet been able to find any books, period or otherwise, that discuss how mezza mandolina is made, I have been forced to reinvent the wheel, as it were. I have been studying period portraits and samples, and reverse engineering the stitches. A lot of trial and error have been involved. The following portrait images have been collected from varius sources (with much thanks to Lady Ranvaig, who shared many with me from her collection).
