For clothes, I just started using this idea. I have a box of clothes that I wanted to either give away or try selling in my next garage sale, but honestly, I'm tired of looking at it.
A friend of mine has a neighbor (the cutest and sweetest little old lady ever!) who told him to save old clothes for raised beds. It goes along with the idea of lasagna gardening (google it if you don't know what it is). In the raised beds, you add a good layer of old clothes. Overtime they will decompose but their main purpose before they break down is to hold moisture! We all know raised beds dry out more quickly. They are great during rainy spring seasons because of their drainage but where I live, in the summer, it is hotter than the center of the earth and dryer than a desert (ok, maybe not to that extreme but sometimes I feel like it is). The point is, raised beds in my area are a pan to keep well watered so hearing this tip was awesome! Before adding new plants to my raised beds (I have only 2 now and they are long and narrow with a large arbor built between them. I use them to grow my vining veggies like pole beans, small pumpkins....) I dug up the soil and put in a good layer of clothes at the bottom. I think this will also help keep down the weeds too! So far, they are doing better than last year :)
Anyways, just wanted to share those tips!

Happy Gardening!
