Sewing the cushions

This weekend I will start sewing the cushions and curtains. Thought I would post a before and after. The curtains should be easy....I've done them before. The cushions...not so sure. I also plan on making a dog bed that fits in the sunken floor. Which would be a 3 X 3 dog bed...and 9 inches deep. I need to find some very stiff foam so the old dog can move around without tripping in the dorf.
