I've taught quite a few players how to draw. Most everyone wants you to hit the ball lower, and follow through which is great advice, but start with just a single striped ball on the table...pick a number as long as it's a stripe. If you have a CB, and an OB on the table, AND you're also trying to make the OB it's just too many things to focus on at the same time.
Place the ball on the table with the stripe running horizontally. Now line up your cue with tip low and cue as level as possible. Stroke through the ball, not at the ball, with the intention of making the ball spin backwards. The stripe will tell you if it's just skidding or actually spinning backwards. I don't care if the ball only travels two feet as long as there's backwards spin on it, in fact the slower forward speed the better. Once you get the ball spinning backwards as indicated by the stripe, then add an OB about a foot or two away...but don't try to make the OB, and use the stripe ball as the CB cause you still need feedback. Shoot the OB and try to make the stripe come back to you after contact with the OB.
Once you get good at that just keep adding a little more distance, and speed using the same stroke that you can now FEEL.
When you feel comfortable use the CB, feedback no longer needed, and try to make the OB
