I’m looking at the left side near the bottom of the racetrack, looking all the way to the top. It’s pretty good but there is some wave in there (if your follow the suits up). Maybe I’m just being too particular. If I use glue will it be too hard to change the felt in the future ?Glue the cloth to the foam, that way when you pull it tight it doesn't distort the lines.
The lines were 99.9% straight on the table in the pic, it surprises me that the image looks like on the right hand side the lines were wavy but that wan't the case.
