"Pin" to the "Hole"

If you really into photography, you should make a PINHOLE CAMERA!
If Lomography has golden rule “Don’t think just shoot”, you can’t apply that to pinhole. You should think! Hehehe. Because a pinhole camera requires a lengthy exposure, and its shutter operated manually. Theoretically, making the aperture is little bit tricky, but practically it’s not that too hard. Just ignore the formula!
Here are two pinhole cameras I made :)

Warm and Cozy

Lock n Lock Cozy

This is my first crochet project. As is obvious to you, the end result is not quite good. I should get more practice to make a neat-new row.
I modify the jar cozy pattern from Carina. And here's the pattern for flowers.
