if you want to cut the prints in 4"X 4" squares to show the individual cats here's what I did.
cut a 6"X6" square of cardboard or something fairly stiff then measure in 1" all the way around and cut out that square. now you have a 4" frame put in on you fabric to where you see what you want, very carefully relpace the cutout and remove the frame, don't let it slip, now put your ruler on top of this template and cut it out. it should be a nice centered picture.
