Welcome! It has gone a little quiet here, but I'm always happy to chat via messages. :)
Tips? I can offer some thoughts if you'd like...
Just keep your shops nicely stocked and work on making your items the most unique and best quality you can. Plus of course the age old beast of always improving your listing photography. Great customer service that is friendly as well as professional goes a long way as well.
Hope this helps a little bit, my virtual door is always open. :)
