My presentation went off well. And look, as part of the content, I even took a stab at charting the språng design for one of the fifteenth century bras from Lengberg castle.
I like how sprang designs so often preserve the overall balance of positive and negative space. In the case of the Lengberg bra pattern, I like the way the clovers fill in the large diamond.
The blue line is meant to represent the limit of the photograph and everything outside it, an extrapolation. I drew in the top line a little too low.
