Awesome Paper user Florent Bonnefoi shares a bit of his process using the LearningPaper tag. An idea Mischa came up with a few days ago, LearningPaper is a way to ask questions and share techniques with our budding Paper community. Use it on Twitter too!

Four steps to “Guillaume” 
(souvenir from a quite drunk evening)
Done with the Paper App, as usual, on the iPad 1 with a the Bamboo stylus
This sketch has been done quite quickly, in about 2 hours and a half, using the black pencil rather than the fountain pen, as in my previous sketches. It appears to be faster, since I usually overlay almost all the draft with the other tools and colors.
As usual, all of the Paper tools were used, but mainly pencils and watercolors.
