What are the artwork guidelines for canvas prints with the image wrap border?

If you choose the photo wrap border, depending on the wrap thickness you select, your image should account for an additional border/bleed (continuation of the image that would otherwise be trimmed off) on all sides : 

For canvases using our standard 3/4" wrap thickness, your image should have an additional 3/4" border/bleed on all sides (e.g. for a 16" x 20" canvas, you would provide a 17 1/2" x 21 1/2" image)

For canvases using our thicker 1 1/2" wrap thickness, your image should have an additional 1 1/2" border/bleed on all sides (e.g. for a 16" x 20" canvas, you would provide a19" x 23” image)
