i would trace all the major elements of the picture - the house/windows/door, the road, the mountains, the hills.
then scan that into the computer, enlarge it to the size that you want the quilt to be, then print it out.
tape the pages to a light source (i use my sliding glass doors) and trace then pattern onto freeze paper or fusible web.
then you cut out the pattern pieces and adhere them to the fabric.
that landscape is beautiful and i'm sure the quilt will look great.
