:: Step 1.

Create a new document of any size you want. We started with 350×350 px sized document with white background. Choose a pen tool (Image 1, shortcut "P"), and draw some lines like shown on Image 2.

Image 2: Drawing the path.

Now if you don’t know how to use pen tool, don’t be afraid to try. It’s simple. You have just 3 simple steps to do a cure like one above in Image 3. 1st step is to click to make a first point, so go ahead and do it. 2nd step is to click to make second point, but you must press and hold left-mouse-button. Now while you holding drag your mouse to make the curve appear like something on Image 2. 3rd step is to release previously holded left mouse button, and make another click somewhere like shown on image 2, but also hold that mouse click and drag in direction shown on image 2, then release it, and you’re done, you have your curve finished.

Now you will duplicate that curve few times. To duplicate the curve choose Path selection tool (shortcut "A"). Click on the path to select it, then hold ALT and click again on curve and drag a copy out of it. Now repeat that about 4 times to get shape like on Image 4.

Ok, now click some in gray area out of picture, and holding that click drag across the paths to select them all. Then, again hold ALT and left click on one of the paths and drag a duplicate out of it. Make something like shown on Image 5.
