Talk about HUGE cushions!
This seating area in my client's kitchen is 12' long, which means each cushion and bolster is 6' long. It's not really much different sewing a very long cushion or a short one, it just takes a lot more fabric!
And because they are so long, getting the covers on and off the back cushions was very difficult. Since the ends do not show, I made the end caps part of the zipper box to alleviate that problem.
This is the 'before.' Let's just say that it was incredibly ugly before and now it looks way better!
