few questions about icons sets.

Hi everyone! I have a few questions to those of you who make icons?

the first question is: do you outline your strokes?

  • when you make an icon in a 3232 square, do you keep a 2 pixel border around your icon (which means putting the icon in a 2828 px square)? I read somewhere that the border creates a breathing room for the icon, but I am not sure this is necessary.

  • what are the main reasons an icons set gets rejected?

Thanks.
