Lay newspaper over tabletop to make cleanup easier. Using a pot, add wine, butter, garlic, thyme and parsley and bring to a boil. In order, carefully layer potatoes, sausage, onion, corn and crab in the pot. Cover and steam for 15 to 20 minutes until potatoes are cooked. Add the clams; cover and cook for another 5 minutes, just until the clams open up. Pour everything onto a large platter or serving tray and enjoy.
