Hi there,
I notice that other illustrators/artists... or people create prints, send their work out in cello envelopes but also have a cardboard backing board in the envelope.
Where do you source this? Is there a name for it? The cardboard backing is what I am searching for.
I know you can get bend proof envelopes, but the card insert I guess is for extra durability...and also easier to remove from cardboard envelopes.
Thanks in advance.
