Good putty consists of whiting and linseed oil. By using white lead with common putty it will adhere better and become harder. Common white putty may be colored with ordinary colors to match the paint or stain which is being used. A little putty kept in a tightly covered jelly tumbler is often quite handy. As putty becomes hard by standing, some persons prefer to keep a supply of whiting and oil and make their own putty a little at a time as they use it. The hand mixed putty is not usually as good as the good grades of machine mixed. Do not use putty in any holes that can be plugged with wood. If the putty is too soft, wrap what you wish to use at one time in paper and in a few hours it will be much harder.
