Here's what I would do, I think. I'd outline stitch all the straight border/sashing looking parts and any other shapes that have enough long straight lines, and there's a lot of them. The other shapes you'll have to do with the darning foot. Feed dogs up will allow you more control when you do this and you can do it with practice. Then, I'd do a small stipple in the negative space around each motif which will make the cats and flower pots and flowers really pop. Good luck with it. Looks like a really fun project.
