I'm preparing to upholster a Duncan Phyfe sofa. Currently it has three separate cushions for sitting and I am planning to replace it with one wide cushion. The problem is that most upholstery fabric I have found is 54" wide and one cushion (and also the sofa back) are 61" plus. I have never seen a seam in a back or cushion, but there must be since fabric is usually not as wide as a sofa. The way the fabric runs, I have to keep the orientation the same. Any advice?
Thanks!
