Our group had one of those octagon folding tops we'd take from house to house. When it was time to change the surface, went to Hobby Lobby and found some material.
Didn't use felt, found something with a little bit of a sheen to it. We thought it improved the table, made cards slide better. Plus more color options. Not sure how marking a line would've worked, but I bet a sharpie and a straightedge would get it done.
Yea thats plan B, mark it myself. I recall reading at this group once about a place thats makes custom felts, markings plus logos. I don't need the logos but might add a mark infront of each player for their cards. My felt would be 48 inch, plus a 6 or 8 inch foam pad
