Sewcialists is a sewing blog. They launched a challenge where the readers had to sew a zero-waste product, meaning, they had to waste as minimum as possible of the materials used.
I made a tote/backpack.
I tried to waste as little as possible. To be honest, I always waste as little as possible. A simple way to do that is to add small details to the product using all the little pieces of fabric that would otherwise go in the trashcan.
