Tie loops at each end of the string

Attach string to Little Gregor

Clip Carabiner to your bag (or other object)

Place Little Gregor 3-5 inches behind and just outside your ball

Let Little Gregor train you to swing the club more inside-out by NOT hitting him

If you’re missing Little Gregor but still slicing the ball, then the issue is your club face being too open relative to the path of your swing. Try closing the club face more at address or adjusting your grip to be “stronger”, which means turning your hands more underneath the club.
