This is one of those optical illusions you often see on Sheldon Cooper's t-shirt from The Big Bang Theory. It's a fun design you can pop it on a shopping tote/ grocery bag. Don't forget you can use your own colours to make it yours. Also don't forget, for the owners of the Wilcom program or the free TrueSizer converter, the original EMB file format is included. This will allow you to get the design to any size yourself. Combine with other designs or inscriptions. For example, you can add a name.
