I've been thinking of getting the rolls of sandpaper for pen turning like this one: http://www.pennstateind.com/store/PKSPSET5.html
Sure looks convenient. But once you figure in shipping, it's pretty expensive. What's the difference between this and the paper backed sandpaper you can buy at any hardware store? Does the cloth backing really make a difference? Or am I better off saving my money and buying regular sandpaper and cut 1" strips?
