From self-portraits to holiday greetings written in crayon, you can't beat a child's imagination for creating a memorable and welcome teacher's gift. The sentiments can be far-reaching, and the gift is virtually free. If you think teachers get hundreds of these mementos, you may be surprised. Many teachers with extensive collections of "World's Best Teacher" mugs would probably trade them all in for one authentic, creative reminder that a great kid thinks they're the best educator ever. Even if you decide to give your child's teacher a different gift, consider including a piece of art created by your child along with it. It's a wonderful way to include your child in the gift giving hoopla and maybe make a special memory.
