Garbage bag hack
All the trash cans except two in my house are small enough so a regular plastic shopping bag works in them. I don’t smoke and I use candles very carefully so there is no fire danger in the trash.
My two big cans are in the sanctum and in the kitchen. They are standard kitchen size cans. But I use 30 gallon bags in them. I know that when I empty one of the large cans, I should go through the rest of the house and pull those small garbage bags. Since the bag in the large cans is so much larger, I always have room to put the small trash bags into the large one.
