I'm no etsy expert, I am new to selling myself, so I may not have "professional" advice. I have done a lot of research, though. But I browsed your shop as an average buyer, and here's my advice...
The first items I saw were your featured items. Then I looked up at your banner and it did really flow- your banner seems focused on your button bouquets only, and right beneath it are mixed lots of buttons and no bouquets!
I think the overall flow of your shop could be improved. There is vintage jewelry in both the vintage category and jewelry category. You have 2 button bouquet categories but there are only button bouquets in the "everything else" category. It seems that if someone might miss what they are looking for unless they search through every category. Your sales might improve if your shop were easier to navigate - check your categories for accuracy, perhaps divide the "vintage" category further, ie. vintage housewares, vintage jewelry, misc vintage. And if your shop is going to be split between vintage and button bouquets mainly, I would try to find a way to alter your banner to reflect the overall vibe of your shop. I have read a lot about creating a "brand", and having something that ties it all together. If someone visits your shop to browse the button bouquets, they may think that the other items were just "thrown in there". But if you make it part of your brand it would all fit together.
Oh yeah, and I think your button bouquets are AWESOME and I love them. That said, I thought to myself what could I actually do with one of these? You make reference to special occasions, and the bridal use is obvious, but what could other uses be? You list some in the baby blue and floral pink listings, but it may be beneficial to either have specific information in all listings or maybe on your main info page. People visiting your shop to find a bouquet would have a use for it already, but others stumbling upon it and thinking they're super cute may need help seeing how it could have a practical use for them. Perhaps extra photos showing how they could be used? A table set with plates/glasses/etc and a pretty tablecloth with a bouquet in the center? Or for the baby shower ones, showing a table where they are at each place setting? Speaking of photos, some of yours are a bit blurry, I would recommend using a tripod or if not available setting the camera onto a stack of books and using the self timer to avoid any shake after pressing the shutter.
Wow sorry that was a long post. Hope you find some of the info helpful and not just crazy rambling! :) Good luck!
