I've had this on my "to do" list for many, many months now. Yesterday I got tired of seeing it on my list and decided to make it. I bought a 6 foot piece of molding at Lowes and the numbers I bought on ebay. All the numbers I saw at local craft stores were too large or too small.
I measured and made lines with a fine sharpie every inch and hot glued the numbers every foot. The chart is going to sit 1 foot off the ground, so there was no need for the number 1. I love the look of it, but I'm sure you could make it more colorful if you just had small children. I'm sure my older boys appreciate this look.
Now I just need to transfer the names, heights & dates from the wall to our new growth chart!
