Lint and fuzz tend to appear on clothes, especially those made of natural materials like cotton or wool, due to a couple reasons. One common cause is the short and crinkly characteristics of the staple fiber, which create lots of little hooks for grabbing onto stray lint (almost like Velcro).
Here are a few easy solutions to this issue:
- Use a lint brush or roller on the affected area to quickly pick loose
- Wash your item (no detergent) with a cup of distilled white
vinegar which relaxes the fibers and looses the lint
- Use anti-static
or anti-cling spray to neutralize any static charge in the garment. Even small amounts of static charge will cause fibers to stick
Or you could always just wear a t-shirt that is the same color as your sweater, then your lint will effectively be invisible!
