I think one of the coolest ways to decorate your home and teach your children is to make them make it themselves. I loved those days when I was kid and my mom would assign us a task of making some decoration for our home (wall painting, wall clock, kitchen timers etc.). It taught us to use our creativity and be responsible for making our own creations. And simply looking at the end product made us feel proud and happy. So, if you have kids, assign them some cool home decor task and be with them when they make that.
