Also for reference, I like to use Krylon brand UV Archival Varnish matte spray. This spray contains hindered amine light stabilizers (HALS) and UV Absorber (UVA) for the maximum in UV protection. Although I print all of our artwork with a printer and inks that are resistant to fading, I still recommend that customers use a spray that contains HALS and UVA to help preserve their work for future generations to enjoy.
I have put these in the tips section in both the quarter scale blogs if you need to find them again. Thank you Carol.
I don't know how people as busy as Carol and the Betterleys make the time to do this but we are so glad they do.
