The wrap zone for a canvas print is the area beyond the dashed lines that are visible in the project editor. This is the area that will be wrapped around the sides of the canvas' wood frame.
This dashed lines are a warning to ensure that no important part of your image is in that area, as it will not be visible on the front of the canvas once the canvas has been stretched around the frame.
Please note: MdBy Canvas Prints are created by hand. Therefore, there is a small amount of variability around the wrap zone. So images placed directly on the dotted line cannot always be perfectly aligned. For best results stretch your image 1/2 way between the dotted lines and the outer edge, or place the image as a background on the canvas so it covers the area entirely.
