Here's a picture from my parents' house. My mom made the curtain, and I think it looks great.
It's hard to see what the fabric and trim detail look like, so I zoomed in:
My mom specializes in pleats and ruffles - you can see her handiwork in my slipcovered armchairs from an earlier post. The quality of both pictures is not that great because I grabbed the stills from a Flip video, but you get the idea.
I've used this next picture before (in my round-up about red), but it fits in this post too, so here it is again.
Now I'm looking at the floors, too. Do you think they're painted wood? It's kind of hard to tell.
And finally, roman shades don't have to be in a colorful fabric to soften a room.
It's not really a fabric, and there are no colors in sight. But there's already a lot going on with this kitchen (in a good way), so I think the simple, natural texture works.
I love the picture of the kitchen below, but after noticing all the pretty roman shades, I can't help but imagine this window with a pretty dress on.
