Sara Morgan's Vintage Solids are luscious & any time I want the look of a solid, but not totally solid, I look to the vintage solids. They have what I call a mottled or blotchy look; looking like they've been tea dyed like we did so many years ago.
So, of course, I had to sew something with the black vintage, to show it off! Love the black with yellow!
Here's a closeup of the Washington Street Studio fabrics.
