When I used up the last of my cling wrap a few months ago I decided not to buy it again. I haven't missed it at all. It's easy to find alternatives and my favorite is using a wet towel (It has to be wet) to cover rising bread dough. Why is it my favorite? Because I remember my grandmother did the same thing.
P.S. Don't be too impressed by the homemade bread. Even though I make a loaf every other day, I use this no-knead recipe. Go ahead, try it. Pretend to be a supermom, wrist deep, kneading bread all day. No one has to know your secret.
