This is my pattern I made.
How I made it:
We stared with a white plat as a back round then I just stuck these little blocks in to it to make a pattern.
First get out some paper glue stick, pencil, scissors and ruler.
Now put your ruler down on the paper 10 cm draw it with your pencil and 7 cm on the side do the same on the other side. My box has 4 corners and 8 edges my box is a rectangle.
