I did 1/2 " hexies, by printing hex graph paper onto freezer paper on my printer. So, working off a photo copy of the kite shape, the same should work for the kite shapes, put a bunch on a single sheet of paper and then copy them on your printer.
The biggest problem I had was in getting the sticky side of the hexies on the fabric. Invariably, I had some that were oriented upwards and stuck to the iron. That shouldn't be as big a problem with larger sized pieces.
