Hey quilt n nan ... That is adorable!
I have set so many one color embroidery quilts and you can design some real original designs if you get creative with a print that has the color of your embroidery plus a companion color. Like red and aqua, or blue and yellow. It frees you up to have more than just a mono-tone quilt.
I have posted a few here if you want to search my posts for inspiration maybe?
