The C-to-C Roll
The C-to-C roll is named after the two arcs your body carves as you proceed through the roll: one horizontal arc from your bow out 90 degrees to your side, and a second vertical arc from an upside-down to a rightside-up position.

The setup.  

Start the setup by tucking your face down onto the deck and placing your paddle parallel along the left edge of the boat, power face up. (This sets you up for a right-side roll, where your body will emerge on the right side of your boat; a left-handed paddler can place the paddle on the right side of the boat to set up, and roll up on the left side.) With your right arm positioned in front of your head, your nose on the deck, and your paddle properly in place, you are ready to flip upside down in the setup position.

The sweep. 

Hold the setup position momentarily, feeling which torso muscles it takes to keep you in a protected position. Then, once you have your bearings, sweep your front blade (the blade nearest the bow) out at a right angle from your boat. Keep that front blade on top of the water, sweeping with a climbing angle, and your front hand as high and dry as possible. As your front blade sweeps into position 90 degrees from your boat, your back arm will need to wrap up and over the hull to give you space to maneuver. If your blade dives during the sweep, you probably have it set at a diving angle (cock your wrists downward more) or you failed to start with your blade on the surface (reach higher during the setup). Again, patience and practice make perfect. You have now completed the first C in the C-to-C roll.

The hip snap/recovery. 

With your front blade at a right angle to the boat, start the second C by bracing on the front blade while simultaneously executing a hip snap to right the boat. Use your hips, knees, and abs, not your arms, to right the boat; keep your head low and relaxed until your boat has righted itself; and try to be fluid and graceful in your motions. Also, keep your left arm (for right-side rolls) tucked close to your body to prevent shoulder injuries.

The Hand Roll

There are many ways to hand roll, but many paddlers find it easier to let their body float up their preferred rolling side, locking their thumbs together to form a big, webbed fin out of both hands, then slapping the water with the cupped hands while simultaneously executing a hip snap.

Any defects in your body position or hip snap will become readily apparent in your hand roll. If your head comes up too fast, you'll sink; if your hip snap is lame, you'll never hit your roll. Fortunately, you can borrow a friend's bow again, practice with your hands on a life jacket, or go back to the side of a pool to work out these kinks. Then keep practicing your hand roll until you have it down pat.
