Hi Samantha,
I love your shop.... love the tree with swing invitation! If I saw these (and could afford them for my daughter's wedding!), I would SO buy them! All of your invitations are beautiful, and well priced.
My personal preference is the simple, light or white background. The wood background isn't as elegant. But your photography is gorgeous.
The more items you heart, the more people you follow, the more your page will be viewed. Relist at peak times. I relist one or two things in the evening... I don't really know if it's the best time or not but I take my best guess. Stalk brides. ha. I mean, look often at your list of "followers", and people who favorite your items. Add them to your circle and find something in their shop or favorites to like. I see you use facebook... Pinterest is also a great place to show off your talent.
Your tags - some are one word tags, and I've taken the advise of many people to use multiple words in tags. Instead of damask, say yellow damask, or damask invitation. or Spring Wedding Invites...
Try to reach as many people as possible. There aren't many shops that offer Hers&Hers or His&His items. Having a few listings for LGBT couples shows your range of diversity and is a way to reach a more diverse group of people. Use a couple LGBT invitation tags. If I were looking for wedding invitations, as a lesbian, I would be looking only at shops who were visibly inviting to our community.
Best of luck to you -- I've added you to my faves. :)
