Roll your clothes rather than folding
Particularly delicate fabrics like silk or linen quickly wrinkle in a bag. But it is feasible to pack without wrinkles: Instead of folding your shirts, pants, and other clothing, firmly roll them up to avoid creases. Rolling also saves room in your travel bags, which is a good side effect. Vacuum bags or specific clothing panniers are a big assistance because they reduce the bulk for insensitive textiles like wool.
