I think I'd call her and very nicely ask if she's had time to look at it and decide which piece she wanted and set up a time to meet with her. With an upcoming wedding she's probably just forgotten.
If she then blows you off I'd say "Live and learn" cut your losses and stay away from her. I had to do that with a friend of mine and it's been funny how my rulers, rotary cutters, fabric and books have decided to stay home. With as much as I gave her you wouldn't have thought she'd steal on top of it. Oh well.
