I don't know about you, but I grew up in a household where our heights were recorded on the bathroom door jam. When my parents eventually sold my childhood home, my mother threatened to remove the entire door frame just so she could keep the scribbles and etchings of all our milestones (... you'll be pleased to know that I did finally make it to 5ft 4 inches despite a harrowing few years hovering around the 4ft mark!).
So when I came across this fabulous 'measuring tape' style height measure on Etsy, I thought it was the answer to every parent's dilemma... when you move, just roll it up and cart it along to the next place... easy as pie! The fact that it looks suitably vintagey and retro is just an added bonus really!
