I feel like sometimes I discourage you from ever posting your available items on your social media accounts. Especially if you’re following me for an example there. I’m SO bad about not promoting my own artwork for sale. I just want to say that you absolutely can and should be sharing your items available for sale. Many of your fans are following you so that they do know when you have new paintings available. You just don’t want to overdo it.
As a general rule, share at least two posts that are non-promotional for every one promotional/sale post. This allows you to let your fans know what items you have, without spamming them non-stop with things you want them to buy from you.
