Abstracted Hand 3D

I saw something similar to this on the internet and decided to make my own. I lightly drew around my hand with a pencil, then using a ruler and a fine liner, I drew multiple lines. I arched the lines as the made contact with the outline. The result was this 3D effect of my hand.

Rose Pattern

I drew around an image of a rose in Photoshop, just keeping to an outline. I then copied and repeated that rose to make this pattern.
