Progress joined 15 top designers in using a theme of sustainability to create limited edition runs of 250 bags each for the Re:Bag exhibition at the The Sea Gallery Clerkenwell (runs through October 11th).  Our favorite of the screen-printed canvas bags is done by BB/Saunders and comes with a green marker to color in a tree every time you don't use a plastic bag when shopping.  Here at TLS, we have collectively saved about 84 bags so far this year by carrying a pack of gum after purchase rather than putting it in a bag first.  Progress specializes in production using a wide range of materials - from wood to anodised aluminum, foam core to holographic PVC.
