I recycle and I make do . Cards are easy to use up trims and pictures saved.
Scrap cards are made from things on my desk. The pictures are some already used from water printing.
The leftover has an aged grainy look. Water color dyed the background card.
Deckle cards look really classic. Got to have deckle edge scissors if no others. Mattting them makes them look professional. White paper inside dark cards so they can be written on.
