New Crafter advice please

Hi. I’m completely new to this site and have recently started creating quirky Planters with personality. It has kept me sane during lockdown and I just love creating these ladies - giving each one its own personality. They make everyone that sees them smile and that makes me so happy. Ive seen nothing like them anywhere and did my first craft fair today which was a huge success so I’m hoping to start doing lots more this year. I will be adding more items onto my store but wondered how others manage when they sell items at fairs do you delete the listing immediately on here. As I use different social media platforms, I sometimes forget to delete a sold item straight away. Any tips and advise for a newbie really appreciated. Xxx
