Here's another wedge drill.

I have read about this in the monthly magazine I get Todays Golfer www.todaysgolfer.co.uk. There is a section where theres a celeb challenge and I think its a great way of becoming very accurate with your wedge. It like this

Take a golf umbrella and place it 50 yrds away from you openned up upside down and place it in the grass. Then hit 10 balls into the umbrella with the object of the balls you hit have to remain inside the the umbrella. Sounds easy dosent it have a go and see how many you get. Now this is a test for accuracy. By the way mine is 1 out of 10

Cheers
