That's a nice video, but the frames don't always fit the painting. Usually they leave parts of the background canvas showing. Usually the canvas has been cut so short on the sides, you don't have any wiggle room for the framing. You are better off trying to frame in one of the other posted methods where you cut off the border around the picture so you don't see all the lettering. As an alternative, get out your white acrylic paint and paint over all the printing before you frame it.
Can you please comment on where you find this type of frame for your paintings? I’ve looked extensively and can’t find the self adhesive kind. Please comment with a link. Your help would be much appreciated! Thank you
