Thanks a lot Rico T. :D
The burger and the coffee cup are all made in the same way, but I m not going to tell you how :) It’s very simple and you will figure it our your self (It is, infact, simpler than the cube). I’ll give you a hint.. You don’t always have to use all the 3 faces (Top, Left and Right), all the time. For these, you’ll probably need only the top view and a bit of pen tool etc. Try it :) Let me know if you need any help. If may readers have the same doubt, I can post a detailed tutorial on that :) All the best.
