Good morning to you all. I am in GREAT NEED of your expertise!!!!!!!!!!!! I have an oversize canvas, 30 x 80. Unfortunately, you have probably heard this story before, the canvas was cut at the edges to a merely 3/4" extra material outside of the image itself. How in the world can I stretch this on stretch boards, ? Is there someother way ...please advise, and know how much I appreciate your time and advise in this matter. thank you, sue
