To make a denim rug from old jeans, you can follow these steps:

1. Cut your old jeans into strips.
2. Weave, sew, braid, or crochet the strips into a rug.
3. Overlap and secure the ends tightly.
4. Add cotton yarn for color and durability.
5. You'll need about 2-3 pairs of jeans for a rug ¹.

Alternatively, you can make a jean rug without sewing by using denim waistbands, fabric glue, and a non-slip rug ².
