holding the violin

The arm should be at about a 105 degree angle while holding the home position on the violin. The left wrist should never bend. It makes it more difficult to hold down the strings. The neck should never rest on your thumb, that is what leads to the wrist bending. The body of the violin should have a chin rest at the bottom. Mostly the left side of your jaw will be sitting in the rest, but the tip of your chin will also be there. The violin should rest between your left shoulder and your collar bone.
