We usually don't have the patience (not to mention the tools or skills) for most of Martha's craft projects, but this no-sew bag sounds easy enough, and the result is so pretty and useful.
All you need is a piece of ultrasuede, some good scissors, and the templates available here, and you're good to go. It says it's sturdy enough to carry fruits and vegetables, so you can use it for a trip to the grocery store or just keep it on your person for any bag-related need. Make sure you read the comments before printing out the template, though, as it sounds like there may be some issues with sizing (it might require 11x17" paper).
