I've been harassing a friend of mine to let me help him recover his pool tables so maybe I could start a little side business as a table mechanic.Well everything was going great until we went to stretch the last corner and I cut the cloth wrong.Now the pocket has a bubble inside the lip that my friend says will cut the cloth sooner or later.I have two questions 1 Is there anything I can do about that bubble and 2 Are there any good videos on table repair/recovery? Thanks in advance for any and all assistance.
