I have thought the other day - how people can use their old jeans .... To sew bags and purses, backpacks, make a shorts and an aprons, placemats, coasters, oven mitts and many many others ideas...One on them is here - denim jewellery! Have a look -
Denim pi brooch or scarf holder and
Denim necklace (pendant)
Small stuff is easy to put in to a pocket - a key, a ring, a small greeting card, candy, pill and etc! Eh-he-hey!!
