Pro tip: Using leftover denim insulation to soundproof interior walls during remodels

I was finishing up a basement insulation job last month and had several batts of denim insulation left over. Instead of sending them to the landfill, I offered to add them to the interior walls for soundproofing between rooms. The homeowner was thrilled with the added privacy, and it made use of material that would have been wasted. It's a small step, but how many of us are just tossing viable insulation after a cut? Finding a second life for scraps feels better and often adds value to the project.
