Sarah (who has been sending me good hacks for years!) offers this germ containment strategy:
I use packaging tape to attach an empty tissue box to a full one (side by side) so that when my kids use a tissue they can stuff it into the empty box. No more stray dirty tissues lying around. Works great when someone has a cold and they are using lots of tissues in a short period of time.
So, so smart. When I empty the bathroom wastebasket, I invariably have to escaped used tissues. This way, no one has to touch them ever again.
