I use both Illustrator and Photoshop. In this one, you can see the second step is me doing the lines in Illustrator, but step 1 and everything after 2 is Photoshop. You just can't beat Illustrator for clean, simple lines. Best of all, when you import an Illustrator object (as easy as COPY in Illustrator and PASTE in photoshop), if you leave it as an OBJECT (it will ask you when you paste what kind of import you want to do), you can double-click the layer any time to take the object back to Illustrator to modify the lines. Then when you save the file, it will automatically update the photoshop vector layer.



Also, what are you doing up so late!?
