Empty your pockets - It prevents the pockets from sagging due to your loose change or keys hanging around in there

Air it out - Lay your knits out flat, it will naturally rid the fabric of outdoor (e.g. campfire smoke)

Brush it - In between wears, lightly brush your garments to remove any dust or dirt that may be come stains later on, this will also help rid the fabric of insect infestation

Drying - Follow the garment's instructions on drying, never tumble dry unless specified; if your wool gets wet, dry it immediately, away from direct heat

Wrinkles - Lightweight garments can be ironed with a damp towel on a warm iron (low heat setting); Woven garments can be hung in a steamy bathroom or overnight to help remove creases (don't hang your wovens any longer than overnight in order to retain the shape)

Moths (other insects) and Storage - These little buggers are attracted to the scent of humans, always be sure clean your wool garments before storing them away. It's recommended to clean them and let them air out in the sun, or a warm dry location before packing away, moths don't dig the sunlight, so exposing garments before storing (and periodically throughout storage will deter any moths). Be sure to pack your woolens in a clean, dry, airtight location. Moths cannot tolerate extreme heat or cold, so if you discover larvae, the safest approach for wool is too shake the garment and then place in a freezer for 24 hours to kill off the larvae.
