Gracie, I have done this many time. It is not hard but you must keep checking often to see that is is aligned correctly. They sell stretcher strips at Michaels, I know there is still one in West Chester I know. There is a tool called a stretcher that helps to stretch the canvas so that the picture will be taut. BTW, are you in TV or WC? Maybe we could get together. I have a staple gun. Sally
