🛡️ Prevention Tips for Future
- Always use cold water (30°C/86°F max) - hot water causes permanent felting
- Never put wool in the dryer - heat is the primary cause of shrinkage
- Use gentle/hand wash cycle only - agitation causes fibers to lock together
- Lay flat to dry - hanging wet wool causes stretching
- Use wool-specific detergent - regular detergent can damage fibers
- Check care labels - some wool is treated to be machine washable
