You could do SID along both sides of the sashing and a circular design centered on the 4-patch. Or you could add a vine moving up the angled road. Nicely done. I did a variation on the theme for my MIL - called Road to California.

can't help with the quilting but I love the color!

Wow, she's a beauty. You could just parallel stitch along some of the straight lines, much easier than SID. How about 1/4" outside the brown sashing from end to end, then around the tan block in the corner, then around the side of the tan/white four patch, around the next tan square, giving you a diagonal zigzag on either side of the squares. Clear as mud, right?? I wish I knew how to "draw" on a picture. I can see what I would do, but I don't know how to tell you! But I definitely would not do a meander.

whatever you do, show us when you're done!

what size are the blocks.

Beautiful!!

the block are 9 1/2" finished

Wow, I love that quilt...colors are awedome!

That is just a beautiful quilt, love your color combination. Stitch in the ditch for the blocks and maybe feathering in the sashing?

I'm watching what the experts suggest, too... and WOW that's a pretty quilt!!

continuous curves in squares, pumpkin seeds in sashes....hard to put design idea into words.....look at some of the stencil sites to get some ideas.....do a lot of doodling on paper until you get something you like, then do on machine. I do my quilting on a LA, so I cannot relate to doing it on a DM. I think if I had to, I would "pencil in" some of the design work before I made the sandwich, just like in handquilting, then it will be easier for you to see where you are in the process.
