I wanted a unique eco-bag, not one from a store, so I made this myself. I've used synthetic fabrics, cotton, and covered buttons. I'm organizing the ones I've made. I hope you'll use them. Size: Please check the images. How to fold (see images): ① Place the bag with the button side down. Fold in from the left and right sides by one-third each, making the width one-third. ② Fold the top and bottom by one-third each, making the length one-third. ③ Fold in half from the top. ④ Hook the loop onto the button. ⑤ If you want to fold it even smaller, you can tie the end of the loop.
