Well, there are several options. One of them is Reddit's horror story sections. Users often share interesting and creepy yarn stories there. Also, check out dedicated horror story forums like ScaryForums.com.
The story of 'The Sinister Yarn Ball' is quite well - known. It's about a yarn ball that grew larger and larger every time it was touched, and it would roll around the house at night, leaving a trail of cold air. Eventually, it became so big that it filled an entire room and seemed to have a life of its own.
One classic scary yarn story is 'The Tell - Tale Heart' by Edgar Allan Poe. It's about a narrator who is haunted by the old man's 'vulture - like' eye and eventually kills him. Another is 'The Monkey's Paw' which has a cursed paw that grants wishes but with terrifying consequences. There's also 'The Yellow Wallpaper' which shows the descent into madness of a woman trapped in a room with strange wallpaper.
Often, there are characters like old women. They are usually associated with knitting and are sometimes the victims of the spooky yarn. For example, an old woman might unknowingly use cursed yarn for her knitting and then face all kinds of strange and terrifying events.
In the app, there might be a story about a cursed object. For example, a mirror that shows a different, more terrifying world when you look into it at midnight. People who look into it start to have bad luck and are haunted by the figures they see in the mirror's alternate world.
One of the scariest yarn scary stories could be about a haunted yarn ball. In this story, a lonely old woman starts knitting with a yarn ball she found in an abandoned house. As she knits, strange apparitions start to form around her. Every stitch she makes seems to bring more and more evil spirits into her small cottage.
One online yarn story I know is about a group of knitters who started an online community. They shared patterns and tips. One knitter was struggling with a complex pattern, and through the online group, she got step - by - step help from others. They also organized virtual yarn swaps, which made it exciting for members to get new and different yarns from all over the world.
There was a yarn that was said to be cursed. A young girl found it in an attic. When she started to knit with it, she began to have nightmares of a dark figure looming over her bed at night. Every stitch she made with that yarn seemed to draw the figure closer, until she finally threw the yarn away in fear.
Yarn can add a tactile element. Just by holding it, it can create a sense of nervous energy. If it's a long piece of yarn, you can trail it across the floor while telling the story, making it seem like an unseen presence is lurking.
