Thank you! I will. Please do provide an update with what she used. I will plan to get whatever it is!Enjoy the chalk. I gifted the chalk to my mother and I once saw denim transfer on the back and then when I checked it a while later it was completely gone and perfectly chalk again. I will ask her what she did. Knowing her, she probably just swiped over it with a wet wipe which is good if that's all it took!
