   Possible Duplicate:   Why does my homemade pasta stick to itself whilst cooking?       I have just made fresh pasta for the first time and although nice it was sticking together. Do you need to leave it after rolling for a period of time or can you use it straight away? 
You should dry the pasta for ten minutes or so before cooking. You can get purpose-built driers that are essentially a series of arms on a pole, or you can improvise with a couple of wooden spoons, draping the pasta over the handles.  Getting the cooking water to a rolling boil helps to keep the pasta moving and prevent sticking also.
