I'm sure you've seen some form of this on Pinterest at some point:
Such a fun idea for a growth chart. We have a small strip of wall between the fireplace and the mudroom door where we had been marking the kids' heights- the same place the previous owners had done. I showed this ruler idea to the hubs, and he thought it was a neat idea, so I set off to find one. I found an Etsy seller who would have been able to make it narrow enough for us, but then hubby decided he wanted to make it himself.
Last night he hung up the final product:
He even added in the metal edge.
We plan to order some hand-stamped metal discs with the kids' heights on them and nail them into the board at the right mark. I think it looks incredible!
