This drill works for any club except driver or putter of course.
Find some room in your garage or basement or wherever you can swing an iron. Place a q-tip on the carpet or fake grass mat instead of a ball and point it in the direction you wish to swing. Let her rip. If you hit the swab correctly, it will fly! Hit it too fat and it goes low along the floor. Swing too high because you pull your heat up or don't keep your forward arm extended, you will miss it altogether. The swab flies like a miniature arrow so you can pick a target (like the middle of the garage door) and it doesn't put dents in the dryer. You will know if you hit it straight or not.
