Evil Mad Scientist Laboratories show you how to make a neat camera cozy! –
This camera cozy protects your LCD and keeps your lens cap on when you toss your camera in your bag or are just carrying it around. It also provides storage for a spare set of batteries as well as a location for the dead ones you’re taking out.
It was designed for the Canon S2IS and S3IS, but the pattern can be adapted for other similarly shaped cameras.
