other to form a larger piece — a shawl, veil or umbrella, for example. This thread was either made of silk or a silk blend, to allow for improper stitches to be easily removed. The mercerization process strengthened cotton threads and spread their use in tatting. Newer designs from the 1920s and onward often use thicker thread in one or more colors, as well as newer joining methods, to reduce the number of thread ends to be hidden. The best thread for tatting is a "hard" thread that does not untwist readily. Cordonnet thread is a common tatting thread; Perl cotton is an example of a beautiful cord that is nonetheless a bit loose for tatting purposes. Some tatting designs incorporate ribbons and beads. Patterns Older patterns use a longhand notation to describe the stitches needed, while newer patterns tend to make extensive use of abbreviations such as "ds" to mean "double stitch," and an almost mathematical-looking notation. The following examples describe the same small piece of tatting (the first ring in the Hen and Chicks pattern) Ring five ds, three picots separated by five ds, five ds, close, turn, space R 5ds, 3 p sep by 5ds, 5ds, cl, turn, sp R 5-5-5-5 cl rw sp Some tatters prefer a visual pattern where the design is drawn schematically with annotations indicating the number of double stitches and order of construction. This can either be used on its own or alongside a written pattern. Modern tatting pattern books sometimes include jewelry items that can be adorned with beads. History Tatting may have developed from netting and decorative ropework as sailors and fishermen would put together motifs for girlfriends and wives at home. Decorative ropework employed on ships includes techniques (esp. coxcombing) that show striking similarity with tatting. A good description of this can be found in Knots, Splices and Fancywork. Some believe tatting originated over 200 years ago, often citing shuttles seen in 18th-century paintings of women such as Charlotte of Mecklenburg-Strelitz, Princess Marie Adélaïde of France, and Anne, Countess of Albemarle. A close inspection of those paintings, however, shows that the shuttles in question are too large to be tatting shuttles, and that they are actually knotting shuttles. There is no documentation of or examples of tatted lace that dates prior to 1800. All available evidence shows that tatting originated in the early 19th century. However, recent research by
