when you want to glue down cloth, go to HD and buy these clips for $1 each, cut cloth to the size of the slate, turn it upside down and use spring clamps on sides after you pull the cloth tight, the glue will penetrate much better this way. then you will only stripe the side of the slate where the 2 inch roller puts pressure on it when its applied.
USE A POOL CUE in the middle of the bed cloth to lift and rest on anything you want after you take off the clips. The glue stripe is right where you need it. Then roller the sides of the slate and under pockets. No need to put cloth on cloth under pockets all over the place because you have already put it where it will work which eliminates ball hang ups.
Put cloth back on just like you did it when you pre stretched it.
Less glue, less smell, more yield per can, I get mine from THE PENGUIN but you can use any contact cement
