I'm curious. What do they use to draw the white lines on the table such as at the World 9 Ball Championships? Are they simply 'soap' marks made with tailor's chalk, or something else? Anyone know for sure? I like the cross at the foot spot in particular for racking the balls. Was thinking about lobbying to get those types of marks when the tables here where we play are recovered soon. Much better than a small dot, or a 'spot' in my opinion, for getting a true, straight rack when playing against some folks that can't seem to rack in line with the table. Thanks in advance.
