Hi, I have this design below (Digital Camouflage). The design is too small to get printed on a rectangular paper of around A2 Size. I want the below artwork to be extended & the same designing pattern of camouflage needs to extended. I will need HD Corel Draw file to the same. I have added a sample design of Blue - Green Shade file. It will only be for reference purpose so that you could produce design.
