Just wanted to know if anyone out there can tell me where I can purchase (inexpensively) backsacks or drawstring backpacks? I need four for my children. We are headed to WDW in Sept and I plan on filling them with items to keep them occupied on the five hour flight down. I have colouring sheets, Disney books, snacks, and other items that they haven't seen yet. They will be taking backpacks onto the plane, so I thought the backsacks would be great as they can fit inside the backpacks. I plan on personalizing the sacks with each of their favourite Disney characters. The only spots that I have found on the internet are already printed (with sports teams) or spots where I have to purchase a minimum of 25 bags. I know I could actually sew them up, but I have a lot of other projects to do before we leave and not having to sew would be great.
