I pride myself on having made the switch from plastic to reusable water bottles long ago but still find myself shamefully relying on plastic sandwich and snack baggies when packing lunch. Not sure what my options were, I spent a little time shopping around this weekend and found a huge market of sustainable alternatives to plastic. Options range from organic cotton to recycled, but all divert waste from our landfills while saving you money in the long run.
Reusablebags has a great selection with lots of different design choices and prices from $3 to $30+. If you have the time I recommend the DIY approach. The crafty people at CraftyStylish can show you how to make a reusable sandwich in a snap.
