First of all congrats on wife wanting to join in bowhunting.... you are in for a fun ride
Shed 's offer is a great idea in my opinion. teach her the right way from the beginning and she will have fewer bad habits to overcome later on.
Patience and Practice are 2 of the platforms to build a solid shooter.
Then get her out in the woods as much as possible doing late winter scouting, shed hunting, spot and stalking for fun let her shadow you to learn, photography and shooting 3D to practice proper shot placement.... put her out in treestands and let her kill em with a camera.... let her walk rub lines it kinda helps to put together the big picture and all off these will help her to get to know your hunting land like the back of her hand... let here shadow you on a bowkill and then have her do the blood trailing , teach her to field dress hands on and haveher participate in the dragging out of a deer... if you have other critters in season once she is proficient with the bow get her out and get her to bowhunt the other critters so she has some bow kills under her belt to help to boost her confidence level before deer season comes in.
And I know you both will have a great time.............
