Embroidery Library has some couples. Even thought they are in colors, just don't chg the thread & make them all one color. There's a Charleston, tango, sock hop & I forgot the other one. Different sizes. Sometimes they have weekend specials if they are too costly for you. Take a look. Just put dance in the search box. LOTS of ballet, but go thru all 5 pages & you'll find them.
