I have Daota sizer software for changing the size of designs. and it takes a while to learn how to do it. but when I open my design in the program I can left click on the design then a box appears arround the design with little square places in the corners and the middle, that when you run your cursor over them they turn into arrows you can drag them and make your design larger or smaller but beware if you make them very much smaller they will get too dense I hope this makes sense.
