Do what you want to do. There are no "shoulds". Just keep in mind that you do risk the rejection as she might refuse the gift. I've been offered gifts by my clients just a few times and I accepted them because I knew they were a pure expression of gratitude with no strings attached and because they were either handmade or of very small monetary value, so I didn't feel that accepting them would compromise a professional nature of our relationships.
