Piecing this project was incredibly easy. By far the easiest project I've ever done in quilting, as there were absolutely no seams to match, no quarter-inch seams to get carefully right, no careful pressing to make sure I don't stretch any edges, basically, it's near impossible to mess up. After the piecing was done, the project is technically all "quilted", but I was not satisfied. Since I chose a gradient batik, and at the darker ends, it just looks like a big slab of color, I really couldn't see the seams and hence couldn't appreciate the texture. I had to add surface quilting to give it some visual interest.
I decided to do a wavy design. I first tried to free-motion it, but it was a disaster, so I switched to the walking foot, and was able to do the exact design I had in mind with it. It turned out better than I expected!
I really love this piece now, and no longer think of it as purely temporary. It works with my dining room very well.
