Q: I just had this bench seat built under a bay window in my dining area. I've yet to finish and paint it, but I'm thinking about cushions. It's a trapezoid shape. I'd love some advice on how to create cushions. Should I cut one piece of foam the shape of the bench, or should I try and cut three pieces? I am a seamstress, and I think I've found some good online tutorials for sewing the covers, but the cutting of the foam is keeping me from moving forward.
