I do not have many memories of my grandfather, however I do remember him using a handkerchief. He'd blow his honker into this ratty cloth and then stuff it back into his pocket. I could remember being grossed out by this display and I was still at an age where my friends would eat worms on a dare!
As I grow older and become more comfortable with who I am and what my morals are, I've been able to shake aside the convenience factor of many day-to-day tasks and opt for the more Earth-friendly choices. Even simple things such as using a bagless vacuum: it can be a bit messier to clean however there is virtually no waste (especially if all that you're vacuuming is kitty dander & dirty carpets). Last Spring, at a friend's wedding, I managed to acquire some napkins which have been put to good use since. I feel guilty using paper towels for cleaning anything except messy spills on the floor, so our dish clothes get plenty of use as well.
But the handkerchief, oh the handkerchief. My achilles. The thorn in my side. The one thing that I can't dive deep into. I try to take comfort knowing that tissues are biodegradable and that they're not that bad for the environment, but the thought of throwing them into the garbage (they accumulate too much in our small compost bin if thrown in) makes me feel bad. If I ever were to start using them, I'd make them from cut up bedsheets, hemmed along the edges. If that were to happen. I doubt it will.
Is using a hanky too much for you? Does it cross the comfort zone?
