Re: Reducing a Pattern for Download
When you enlarge that image, you are enlarging a raster image. That means it won't scale well because all the pixels are static. Vector images will scale because the shape is mathematically made.
2 options
1. Your best bet is to keep it the original size and tell people they will have to print it and piece it together.
2. Save it as a vector image that will scale well, but this means you will be saving it as a photoshop file or illustrator file and only the people with those programs can access it.
Hope this information helps.
