Flannel weight is measured in ounces per square yard. A 5-ounce flannel is standard for winter. Six-ounce flannel offers extra warmth but can feel heavy. Four-ounce flannel is lighter and better for mild winters. Consider your sleeping temperature. Hot sleepers may prefer a lighter weight. Cold sleepers should choose at least 5 ounces. Remember that heavier flannel may take longer to dry.
Wash flannel in cold water to prevent shrinkage. Use a gentle cycle with mild detergent. Avoid fabric softeners, which can coat fibers. Tumble dry on low heat or line dry. Remove sheets promptly to reduce wrinkles. Over time, flannel gets softer with washing. Proper care extends the life of your sheets. Always follow the manufacturer's instructions.
