Great tutorial but steps #6 & #7 were way too much. Why not create first a single line with a dark color - done. Next create a second line below it with a lighter color - done. Then click the second line and ctrl+shift (WIN) and drag evenly and below - done. And then ctrl+d until you have all your lines. For the life of me I could not figure out why use the Appearance panel at all to create 20+ lines when you could accomplish the same feat in far less time.
