finally found a material we like, a product made by Ultrafabric called Ultraleather. Kinda pricey but we won't need too much. We are currently trying to get together with the upholsterer so that we can get an accurate measurement and a time frame. we've been using the boat with the blue bottom cushions, the backrest is still sitting in the garage waiting for material to arrive. so now it is a project in motion. but as long as we can use it and the admiral is ok with it, i'm good.
