Decorate my mantel?
Hi Mary: Put whatever makes you happy on it, your home, your rules:) If you put things of varying sizes, put the tall ones in the middle and the shorter ones on the sides, or vice versa. But, the decorations should be whatever makes you smile when you look at them. Make yourself happy, not what some book or decorator says you should do. Good luck
Use items that fit your style,and makes you smile
