I guess I need to buy two, one for a back up slider and one for my oven. When something spills in the oven I just turn on the self cleaning cycle. I give my neighbor, Queen of Green, panic attacks. I run my dishwasher with maybe a couple of pots in it, wash and dry small loads of laundry, use disposable dishes,cups and utensils for every meal, my trash pick up is always full, won't turn off my yard lamp that comes on at dusk and stays on until dawn and I refuse to keep the house below 76 in the winter or above 72 in the summer. Buying a oven liner will make her think I'm maybe changing my ways. :lol: :lol: :lol:
