The rivets should be placed at 3", 6", and 9" across the back. To attached the fabric to the wood, drill a hole first that is appropriate to the diameter of the rivet you're using. Then insert the rivet into the fabric, and into the wood. Be sure to use rivet washers on the back of the rivet for extra strength. Use a riveter to squeeze and snip off the mandrel (the long, skinny part). Riveters can be bought for about $20 at The Home Depot. Warning: Riveters are HARD to squeeze! Use help if you've got a small or weak grasp.
