Check out this Old Schiffili or Schiffli Machine Video, I'm sure this type of embroidery is still done today

Most companies whose primary business is Schiffli embroidery are relatively small and privately owned. Schiffli lace is produced by a machine with several hundred needles placed horizontally one above the other. With fabric held in a frame covering the full width of the machine, the needles move back and forth through the material. The yarn used to embroider the fabric is supplied from individual spools.

Schiffli lace is a type of embroidery that once was made by hand with needles that were pointed at both ends. The lasting popularity of handmade lace led to the invention of lace-making equipment such as Schiffli machines. Many types of lace are machine made, frequently with geometrically shaped netting used as backgrounds. Although previously made only from cotton, Schiffli lace, like other laces, can be manufactured from man-made fibers.

More than 200 companies operated in this industry in the early 2000s, compared to 357 Schiffli machine embroidery companies, with a total of 6,000 employees, in 1977. New Jersey and California had the largest number of companies in this industry. Capital expenditures were roughly six million dollars, with nearly one million dollars going for buildings and other structures while roughly five million dollars went for machinery and equipment. The total cost of materials was $155 million in 2000. The value of shipments in this category was $271.5 million in 2001, up from $179.9 million in 1997, but still less than the $320 million worth of good shipped in 1995.
