Do you use tissues or handkerchiefs? I had someone challenge me over the use of tissues because of the impact on the environment. I use tissues and then dispose of them in the bin as I do not like the idea of germs being in a handkerchief and then using them again and again and having them in your pocket. I do not like the idea of washing them either. It does take water to wash them and this also has an impact on the environment. What are your thoughts?
