The backing is cream-colored flannel. For the batting I used a natural cotton batting, which seemed fitting for this antique-y quilt.
I used a different fabric for each piece (not including the border) and a different embroidery stitch for each line. Luckily my library had an embroidery stitch encyclopedia. Phew!
This border is called "Prairie Points". You fold the triangle pieces, stick them between the quilt layers, and then topstitch the edge of the quilt. (Easier said than done!)
