You can make the bags and totes lined or unlined (they’re jeans material, after all). Just be sure your seams are sturdy. I like the look of adding the white trim on the edges and the bright contrast it makes with the handles and jeans material. Don’t throw out the waistbands or tags, either. Use both! I hope this inspires you to upcycle those old jeans, even if they’re not Levi’s. :P
Editor’s note about Levi Strauss Jeans Projects: Even the zippers can be repurposed. I have used those sturdy, metal zippers in my own motorcycle gear to replace damaged wrist zippers. They last much better than their plastic counterparts!
