Tiny holes in the sheets
Tiny holes in fabric appearing out of nowhere are one of life’s greatest mysteries. They can be incredibly annoying when you have guests, and you know you are placing clean sheets for them. And it turns out that they are clean, but not exactly whole. These tiny rips look so ugly and unhygienic. The first thing that comes to your mind is that some insects or mice ate it.
The real reason is quite simple: the tumble dryer causes these tiny holes. The drum is probably misaligned, and the clothes get caught by it. Fix your tumble dryer.
