To maintain the quality of your flannel onesie: Machine wash in cold water (30°C/86°F) on a gentle cycle. Avoid using bleach and fabric softeners. Tumble dry on low heat or hang dry. For best results, wash inside out to preserve the soft texture and vibrant colors. Do not iron directly on printed areas.
