In this tut i'm going to show you how to draw a symmetrical drawing ^^.
First open the java tool.
Then draw some lines using the Beziers tool. Brush size 5.
Make the lines pretty to look at xD
Use a little bit of shading...
I suck at shading, so don't try to shade like me ^^
Then go to the menu on the left, click on edit, and then on copy.
Open a new layer (I only used two layers.) and paste it there. Then go to effects and select flip horizontal. This is what you should get.
You can also go to effects, and select invert.
That was my tut, good luck ^^
