If you have a kid, you definitely have a ruler to measure his or her height. If you don’t have it yet, have a look at this tutorial. You’ll need to stain 1x8x6 board of pine wood with wood finish. Let the stain set into the wood for a couple of hours because the longer it sets the more deep it soaks in and the better it looks. Now make the numbers: draw the numbers on the paper and transfer them to the board, now use a thick point black paint marker. Then you need to hang it – take your kid and have a look how tall your kid is and hang it as high as he or she needs. Here is a nice idea for you and your kid.
