- Compost: if you purchase 100% cotton underwear then just cut the tags, the elastic waistband, and then cut up the natural material into smaller squares so it can breakdown faster in the bin
- Cleaning rags from softer material or scrubbies from harsher material
- Stuffing: cut up material and use as stuffing in pillows or pet beds (you can do this with socks too, dogs especially would like a dirty sock of yours to sleep with!)
Bonus! Scrunchie: okay this one is a little weird but underwear in good condition would make a great hair tie!
