Oh yes, it's possible. I did that same thing for mom when she brought a kit home she had purchased while on vacation. If it has a copywrite, which it probably does, you can't sell it. Even with the changes I wouldn't try to sell. Mom's is just for her & will be passed down if anyone wants it.

You will need to graph out the new words. "Class" or "Room" will fit better than classroom. "Kindness" will be pretty small to fit in the same width area as "love".

Marz is right. Class or room would fit much better and kindness will have to be much smaller. There are many alphabets available that you will be able to graph. Pam
