You may wonder what pillow recycling has to do with the garden, but I have found a great use for old pillows. Rather than throwing out a pillow as soon as you have bought new ones, I use them for kneeling on in the garden.
It provides a lovely soft surface for the knees, plus it also protects the back because if you are planting or weeding you are not crouched or bent over. This way it is a much more ergonomic way to work.
These pillows eventually make their way into the rubbish bin, but not before they have served a very useful secondary existence.
