I have just completed the final version of “LUNCH”. It is a fully insulated lunch bag, borrowing from the old paper bag for it’s design cues.
I have used blue closed cell (think camping mat) for the insulation, that is then sewn inside the walls of the bag. Our up-cycled billboard banner vinyl was used for the material.
The patterns, vinyl, and how to manual will be available for everyone at the Makerspace, so you can make your own LUNCH.
