Sharp, slender objects used to fasten things together. Unlike sewing needles, which have a hole used for drawing thread, pins have a head like a nail, but smaller, round, and usually made from plastic. They are commonly used to secure fabrics for sewing or stick papers and photos to bulletin boards.

FAQ
Does NovelAI recognize pin?
Compare the samples on this page. Every tag on this site shares the same seed and base prompt, so any change you see comes from pin.
How do I write pin in a prompt?
Write "pin" near the front of the prompt and separate it from other tags with commas.
Should I use V5 or V4.5?
V4.5 shows the tag's effect more strongly. V5 gives steadier images with fewer artifacts.
