This foam is great quality, but when covering a poker table rail this isn't the best product due to the seams. I sprayed and glued the seams as much as possible, but you can still feel the seams in the finished product. Thankfully this isn't much of an issue with my table as the seams are in locations that people will not be sitting all too often, due to the dimensions of the table. I would recommend getting a single sheet of foam and then cutting it off the rail after it has been glued.
Material works fine for a straight line surface, however, a curved surface requires a lot of cutting and fitting small pieces. A solid piece of foam wide enough to cover the entire project would produce a much nicer finished project. The waste could be used for other applications.
