Your shop is lovely! :) I didn't get to see it before, but it's clear that you've put a lot of work into your photos, and your products are very cohesive.
You've obviously had some sales already, but if you want to get to the point of steady sales, the trick is to keep listing steadily. You will probably have seasonal swings since your items are primarily geared toward weddings & special occasions, so expect that and plan accordingly :) You can take advantage by listing/ renewing frequently during early spring.
best of luck with your shop!
