quilts for sale
they are based in Canada but have many US quilters.
or Etsy is another place.
i would think the price on that quilt is way too low! sometimes people will not pay it if they think its too low too...they think they are getting crap.
for a quilt with that investment- and that size i would not offer it anywhere below $750===and would probably start quite a bit higher than that.
