If you made a shop to make icons or avatars, Stick to it! IF the topic is really sucessful, keep it up! Just dont quit without saying "Im done makeing this". Stick to your shop!
If you cannot keep up with your shop or want to close it, make a notice. Say in your topic im done makeing icons or avatars or etc.
So stick to your shop! If you need to close it, make sure you let people know!
