Good question. Initially the kit was going to be small enough to fit in the coffee can. Quickly I realized it would be inadequate for their purposes so I decided to expand it. I obviously wanted the bag to be durable. I went to a local store called 'ollies' which specializes in low cost items that they purchased from stores going out of business.

I found some very durable american tourister tote bags for 2.99 each! There were only 3 (worked out perfectly), brand new, and built solidly. I'll post pictures whenever I find the transfer cable for my digital camera. My thought was 'well, if they don't like the kits at least they'll get some really nice bags out of it!'
