Yes, kristakz, it makes sense to some of us, but it may be easier to visualize if you cut several pieces of paper 2" square. Then lay your border fabric on a bed or table, lay the quilt top on the border fabric, leaving a 4 inch reveal of the border fabric. (just try it with one side or perhaps 1/4 of the quilt so you would have a corner too). Now lay the paper squares on the border fabric and move them around until you are happy with their positioning.
You know that you will need 1 1/2 inches of border fabric on each side of your (finished) 2 inch squares (2 1/2 inches unfinished) to make them as wide as the rest of the border fabric. So really at this point, all you have to do is decide where you want the floating squares, measure the distances, adding seam allowance of course. Do one side at a time.
Cute quilt. I wonder if you could fussy cut squares that would include a butterfly.
