I never thought embroidery hoops could look so charming as wall decor. Do you remember the embroidery hoops from Home Ec class that kept your fabric taut while you did your needlework (Boy, my old Home Economics teacher would be proud that I remember so much about my Sewing Class! See related post here.)? Apparently, they can also decorate a room!
And if you don't want them on your wall, you could also use them as a bulletin board.
