Go to the other end and do the same thing. When the cloth is secure, use a razor blade to cut holes in the cloth where the rail bolts will come up to the rail. There are three holes between each pocket. Use your finger from the bottom up to find the right hole. Never try and find the hole from the top down.
Some tables have more than three holes on the top.
A cut in the wrong place may ruin the cloth for the whole table. Once the holes are done, the pockets are ready to be cut. Make at least three slices on each pocket. The middle pockets will usually need four. You don't want to cut the cloth too close to the actual playing surface.
