For all of you who have a wood growth chart how do you make markings on it. I have decided to get a 6ft cut of wood and apply a decal on it that I ordered on etsy. I will also have our family name on the back of it. I just wondered. what is the best way to record her height on it? I still want to wood growth chart to look good and have enough space so that my future LO's heights can be recorded on it as well
