It is a piece of coarsely woven linen, square, one Flemish ell on a side. She has left a margin all round the edges of about a hand's breadth. The area in the center, then, is a square perhaps eighteen inches on a side: suitable for an opus pulvinarium or cushion-cover. This area has been almost entirely covered in crewel-work. The style is called gros-point, a technique that is popular among English peasants, overseas colonists, and other rustics who amuse themselves sewing naïve designs upon the crude textiles they know how to produce. As it has been superseded, in France, by petit-point, it may be unfamiliar to your majesty, and so I will permit myself the indulgence of a brief description. The fabric or matrix is always of a coarse weave, so that the warp and weft may be seen by the naked eye, forming a regular square grid à la Descartes. Each of the tiny squares in this grid is covered, during the course of the work, by a stitch in the shape of a letter x, forming a square of color that, seen from a distance, becomes one tiny element of the picture being fashioned. Pictures formed in this manner necessarily have a jagged-edged appearance, particularly where an effort has been made to approximate a curve; which explains why such pieces have been all but banished from Versailles and other places where taste and discrimination have vanquished sentimentality. In spite of which your majesty may easily envision the appearance of one of these minute x -shaped stitches when viewed closely: one leg running from northwest to southeast, as it were, and the other southwest to northeast. The two legs cross in the center. One must lie over the other. Which lies on top is a simple matter of the order in which they were laid down. Some embroiderers are creatures of habit, always performing the stitches in the same sequence, so that one of the legs invariably lies atop the other. Others are not so regular. As I examined the Countess's work through a magnifying lens, I saw that she was one of the latter – which I found noteworthy, as she is in other respects a person of the most regular and disciplined habits. It occurred to me to wonder whether the orientations of the overlying legs might be a hidden vector of information.
