We prefer to have at least 1.5” (4cm) between where the painting ends and the edge of the canvas. This gives us enough wiggle room to ensure the canvas can be pulled back and properly secured at the right tension to ensure no wrinkles form in the work over time. If your gap is less than 4cm we recommend you pop down to one of our outlets and we can discuss options. Alternatively, you can take a photo of the work and the gap that exists and drop us an email or chat to us via our livechat. There is always a solution!
