I have made 12'' squares. Well after sewn together... The d9p. How many squares across and how many down?? Would like it to fit a full or queen size bed. And maybe two borders around the out side.

And also is stitch in the ditch just that I'm going to stitch where any two pecies come together Right in the middle of them??? Ooooohhhhhh!!! Please help. Thanks
