My bags and sacks are made of reused and recycled material which I gather from charity shops around. This way I am trying to give new life to items, and mostly to avoid using new made material, because I thing we had produced so much, so now it is time to reused and recycling what we have.
Most of them are reversible, so you can use side which you like more.
They are very simple, one and only pattern is uneven pattern of dye and some tiny embroidery and also contrasting threads for sewing.
