Hello Guys!! This is my first post here, so if I am doing something wrong... I am sorry =/ So, I am really trying to make the salt & pepper effects from the google illustrations and I am failing hard. https://medium.com/google-design/salt-pepper-the-art-of-illustrating-texture-c962dc67cc35#.f0q6cw9rs <--- Here's the reference article. Links from resources, or articles based on affinity designer are a really good tip for me too. Thanks very much!
