That’s good advice Steve gave you. If you can get some arrows to fly reasonable well now, just make a few and shoot and have fun. As your form develops you might be making adjustments to your arrows anyway. It’s easy to get frustrated and frustration ain’t your friend.
Look for moebow and follow his advice on blind bale shooting. I didn’t do it in the beginning, but think it’s a great idea. I do it now and then, mainly in the dark and it does help you concentrate on your form. enjoy, dwc
