I think the leaves are supposed to be oak leaves, which are symbolic of endurance, faith, and strength. This particular pattern might not be the ideal pattern for adaptation to school colors. But there are many more creative minds on the chat than this coffee-starved individual. 😊

Go ahead and change the poem to any colors you choose. Not sure about the leaves. I'm not think colors here; I'm thinking about the challenge I, personally, would have finding the right flowers to fit the border. You could stitch the border with no flowers or leaves leaves; just a frame around the poem. You probably could find a pattern for the frame with a non-floral embellishment in the corners. Remember the instructions and supplies list are SUGGESTIONS! If you buy a kit and modify it in any way to reflect your own views; -- you are an artist.
