Would you be mad if you made something for someone only to find out they are trying to resell it?

I make hair bows and list them on Etsy. I just mailed off an order of 22 bows to a lady 2 weeks ago and then the same bows I just made for her she is now listing them on Etsy claiming to have made them herself. I know it's the same lady I sent them to, and I also know these are my bows that I just made for her. Do you think this is right for her to take credit for my work? I don't care so much that she is reselling them, because I got paid for them, but to claim them as your work when they aren't? Would you be mad? Would you say something to her?
