Camera bags seem to be a thing of the past. Folks are looking to carry their goods on the go inside messenger bags, backpacks and purses. Such things aren't padded to provide enough security for expensive lenses, so why not make your own DIY solution? This carrier can go from bag to bag in a snap!

Advanced sewing and sewing machine skills is one craft I wished I picked up specifically for awesome 'hacks' like this. This is not really a hack but I would definitely change the way some things are worked with this skill.
Also, good job.
Or for those of us less able to sew, go to Crumpler.com and buy a Haven camera pouch. Their bags are fantastic, fit in all sorts of bags, and stand up to the perils of traveling (well 2 years so far...)
Timbuk2 also makes a camera insert for their bags. You could easily slip it into your bag of choice though.
I vaguely remember the issue of foams off gassing and possibly causing damage to expensive camera equipment when I was researching making my own insert a few years back. I decided to err on the side of caution and just purchase an already made insert.
Domke also offers inserts of varying sizes that can be used with their bags or put into your own.
