Sometimes you just run across an idea that makes sense. I found this on MakeProjects
A way to leave a piece of history when you move from that first apartment or beloved house where you raised your little ones. I get a little emotional just thinking of the houses we've left behind. Many transfers along the way, we left a little piece of our heart in each one of those homes. This might be the perfect way for a child to say goodbye to the home where they learned to ride their bike or lost their first tooth. Dropping the note down inside a wall (if you have access to the attic) would be one way to write about your life there, but this idea to put it on the back of a switchplate is almost too good. Not only will you enjoy doing it, the new owners will undoubtedly find it down the line! Complete instructions are at the site, including a PDF that makes the script tiny enough to fit the back of the light switch perfectly!
We've lived here almost 7 years now, I've really put down roots in this house. This is what I would write... "Even though we haven't retired yet, we know this is where we want to grow old. We've spent many happy summers coming back from the lake, walking in the door with wet towels and empty picnic baskets. It's the house where Ben was King and River Ran. It's been our haven on cold, icy days and it never failed to keep us safe. Our life and our love grew here, just like the trees in the woods. As much as this house meant to us, it's the land it sets on that we loved the most. The wildlife that still calls this mountain home shares this land with us, but it was their home first!"
So, what would you say about the house you live in now?
