Personalizing is important to every project.
Take for example this wreath. When we initially met, this wreath was just a plain pinwheel of straw. Today, with fall leaves intertwined into the shape, it hangs proudly on my door (during the Fall months.)
Don't ever think that because something is sold as a finished product it can't be altered. Putting your personal touch on projects not only makes it more valuable to you, but means you won't ever have the same decorations as your neighbor!
