Art Greeting Card

I found a really simple and not-expensive way of creating greeting cards with my art on it: 

• Some time ago I bought a pack of blank white greeting cards with white envelopes from Amazon. 
• I scan my art, do a bit of additional design on Canva and upload them to the drugstore in my neighbourhood.
• I have all the 16x10 cm photos in a small booklet which can be easily carried around and shown to friends and people I know.
• When somebody is interested in getting a certain card, I just glue the photo on the greeting card.
