I'm male and I'm only two months into a new job. There is one colleague in another department, a woman, who I don't currently work with (and, sometimes, don't even meet in the office during the day), but because I was placed in the room of that another department, I became acquainted with her. Her birthday is coming up, and there is a fund raising going right now for a birthday gift.
I'm not in a good financial situation right now, so this is not an option for me. Which is not an issue at all, because fund raising is not obligatory in any sense or way, and even partly anonymous.
However, I would like to make a personalized handmade gift, which comes from a hobby of mine. Personalization of the gift comes form one particular episode during my work here, when she helped me in a way.
So the question is: is it appropriate to make such a gift to a coworker, who I am not very close to?
P.S. I'm sorry for my bad English and weird wording. I'm using a throwaway account and I trying my best not to disclose any information because of the awkwardness of situation and myself about it.
