hey-------ideas: (sorry if they're not what you can make/won't be good/ take to long etc)
-what about if you got on of those big water bottles and like decopauge or stickerize it with her name or different sayings....
- if you can weld/do things with metal then make her one of those tennis ball holders
- sew a cover for a tennis racket with like her initials maybe
-what about if you made her a bunch of granola bars for her to take when she hikes
-what about if you like decorated a visor/hat with stuff
sry that's all i can think of
hope i helped anyway and happy new years
