Line & Fill Icons

Part of an icon set I'm currently working on for an iOS app.

I've finally feel like I have a handle on creating icons like this in Sketch, though some of them I had to go back and forth between Sketch and Illustrator to wrangle the vectors like I wanted. The biggest trick is getting them all within one object so you can change the color with one click. See the attachment for a peek at how the layers are setup.

Would anyone be interested in a blog post about doing this?
