Collage.com's gallery wrap canvases have three different layout options found in the "Edge Options" section under the Photo Fit tab to the left of your project.
This will give you three crop options.
- Custom Crop will put a small border around the front of the canvas that'll print white or the background color you choose.
- Cover Front will bring your images to the edge on the front of the canvas. The sides will be white or the background color you choose.
- Full Wrap will stretch your images across the front and around the sides.
Anything within the dotted blue line will be printed on the front of the canvas. Anything outside of the blue dotted line will be printed on the sides of the canvas.
