GLA nailed what I had in mind! I sent a couple of photographs of existing aquascapes that I wanted GLA to mimic. They showed wider diameter pieces and large knots. GLA was able to deliver with a custom Riverwood arrangement that met all my expectations. They showed me a photograph of what they came up with and gave me the option to approve or adjust. Of course, no adjusting was required. They simply weighed the pieces and provided me with the Qty to order off the website. All of the back-and-forth with GLA was done through email, and they were always prompt to respond.
