at our local farmers market there is a lady who sells quilts all day long about the size you stated, with poly batt & backing...she sells them for $45 each. double your costs and try, but i don't know how well it will sell, it really depends on LOCATION LOCATION LOCATION. i spent one summer selling (beach quilts) they were about 60" x 72" we sold about 40 of them for $125 each...(at the same market as the $45 lady...it just depends. good luck
