Is this something parents would want

I made wooden height chart sticks for all 5 my kids. I wood burn for a hobby so have the numbers and all that burned in and have burned their names, bdays and some art into the tops of the sticks to customize. Each kid has one and for us it is a good keepsake. Several friends and family have asked me to make them for them too. Is that something parents would actually buy?? I am looking for a way to make a little side money (not much but just a bit extra to put in kids college fund and savings)so seeing if height charts like that would actually be desirable. Amlnd by sticks I mean like a small board not a literal stick, like 3 inch wide and 1/2 inch thick and 6 or 7 ft tall....though I could do an actual stick I guess haha.
