Ursula,
I'm new to Etsy, and have been reading the Seller's Handbook and watching Online Labs videos to learn as fast as I can. From what I've learned, having a consistent aesthetic helps. For instance, picking a single, or a few very similar backgrounds against which to photograph all your items. Right now there are some against white backgrounds, and some with grass behind them. Also, I think your items would stand out against a neutral-shade background better than white. Because most of your items are very light, they don't contrast well with a white background- maybe you could try a light grey, beige, or tan of some sort.
Hope that's helpful!
