A very good quality sheet with sturdy fibers and solid construction. By following two simple rules, this lovely flannel will outlast this decade. One: Before using, launder in cold water with one half cup of vinegar (no soap) to set the fibers and minimize future pilling. Two: In future launderings, keep the soap to a minimum and dry on low heat. Never dry for too long or too hot. This will break the fibers that were so carefully napped.
