The difference between the working of the lattice-like band at H, and ladder-stitch G, is that, having completed your first triangle, you make, by buttonholing a stitch, a second triangle pointing the other way, which completes a rectangular shape.
24. BUTTONHOLE, CHAIN, AND KNOT STITCHES.
In the solid work shown at J, you make five buttonhole-stitches, gathering them to a point at the base, then another five, and so on. Repeat the process, this time point upwards, and you have the first band of the pot shape.
Characteristic and most beautiful use is made of buttonhole stitch in the piece of Indian work in Illustration [24], where it is outlined with chain stitch, which goes most perfectly with it.
Cut work, such as that on Illustration [65], is strengthened by outlining it in buttonhole-stitch.
Ladder-stitch occurs in the cusped shapes framing certain flowers in Illustration [72], embroidered all in blue silk on linen. It is not infrequent in Oriental work, and, in fact, goes sometimes by the name of Cretan-stitch on that account.
