This website has several that you can buy. Is there something special you are looking for? What are you putting them on? Tablerunners and small things work very nicely in the embroidery machines but some machines get a little fussy about the weight and drag of the larger quilts, last time I tried that on a big quilt I ended up spending three time the amount of time to pick them out.
Good luck with your search,
