Can you use PVA to seal a paper picture?

Yes, PVA (polyvinyl acetate) can be used to seal a paper picture. It acts as a clear adhesive and can provide a protective layer over the image, helping to prevent moisture and dirt damage. However, it's important to apply it carefully to avoid warping the paper or causing the ink to run. Always test on a small area first to ensure compatibility with the specific paper and ink used.
