Quilting an Improv Quilt

How would you quilt improvisational patchwork?

That's been my challenge for the last few days.  The photo is of a small part of the quilt. About a third of it is pieced like this, another third has irregular stripes, and the remainder is plain white.

I'm not sure this really works, but here's what I did in the "slashed stripes" section shown in the top photo:

Sort-of continuous curve. I wasn't sure how this would look with the irregular-sized squares and rectangles. And like I said, I'm not really loving it, but it looks OK when you see the whole quilt. (I'm not showing the whole quilt here because it is not my quilt.)

The striped section has a mixture of egg-and-dart, ribbon candy, and big feathers in the widest stripes:

And the large section of white background has this "feather meander" filler:

This filler also surrounds the appliqued name I stitched down earlier in the week.

Now the quilting is finished, and it is time to bind it. The binding fabric seemed to have some marks on it, so I've washed it and it is hanging out to dry (or freeze, more likely tonight). But maybe the fabric was a hand-dye, because the marks didn't come out, but huge amounts of dye did.
