We've lived in 7 houses/appartments in our 10 years of marrage, and 9 of those we've had kids, I always wanted to mark up the back of our pantry door with their hight and age but what would the point of that be? so after all this time I saw this on pinterest and fell in love! So I immediatly made one.
I just bought a 1x4x6 (it would be cuter if it was like a 1x6x6, but I have this little corner wall in our kitchen were I wanted to hang it), stained it, marked the inches and drew on some numbers! I started at 6 inches so it would be able to be hung and so my tall husband could mark his hight.
