Pern

Pern is a fictional planet created by Anne McCaffrey beginning in the 1960s, the setting for the Dragonriders of Pern series of science fiction books. In the story it is "Rukbat 3", the third planet in orbit around the star Rukbat, counting outward.

No Pern fiction has been published since June 2012, several months after Anne McCaffrey's death. There are two collections of Pern stories; twenty-three novels, some written jointly or solely by Todd McCaffrey, the son of Anne; and a few authorized companion books by other writers. The figure shows the habitable portion of Pern's northern continent and a tiny portion of its southern continent, which are the setting for the first novel Dragonflight (1968) and its sequel Dragonquest. East–West it shows approximately that hemisphere known prior to the last two books (2011, 2012). North–South it does not show the abandoned region of "Landing" and early colonization, further to the southeast, whose rediscovery and resettlement is one unifying theme of the stories that follow Dragonquest in Pern historical time, perhaps one third of the series.

Thread (yarn)

Thread is a type of yarn used for sewing.

Materials

Thread is made from a wide variety of materials. Following table lists common materials, a general description and what they are supposed to be good for. If your machine will sew with the thread, any thread can used for just about any purpose. This is very useful for someone who is trying to learn sewing. However, it should be remembered that where a thread is stronger than the material that it is being used to join, if seams are placed under strain the material may tear before the thread breaks. Garments are usually sewn with threads of lesser strength than the fabric so that if stressed the seam will break before the garment. Heavy goods that must withstand considerable stresses such as upholstery, car seating, tarpaulins, tents, and saddlery require very strong threads. Attempting repairs with light weight thread will usually result in rapid failure, though again, using a thread that is stronger than the material being sewn can end up causing rips in that material before the thread itself gives way.
