There are several locations where the available rail side space is very slim. Ideally I would like to portray a Pennsy stone wall. I have the wall material in interlocking foam but unfortunately it is too thick for usage. My desire is to not have spliced joints every 2' but rather a 8'+ run in a three locations. Heights range from 5 to 8 inches.
The gentleman who traded as "I love bridges" made a really nice foam based wall 10' long for me but he sadly passed away. His detail was exceptional.
