I would try and get in touch with teams and others that followed you before, let them know you are open and available again. Other than that, just jump in and start over.
Do the same things you would do as a beginner. Get your name out there, and work on making your shop better. We all strive to make our shops better. Good luck.
Blog about a huge big 're-opening' of the shop and spread the word across social media. Maybe, if you can, offer a little giveaway OR a discount coupon for the winner?
