Children's drawings can be used to create greeting cards, stationary or invitations. When creating multiple cards with the same design just scan the design and then set up 4 drawings per page. Cut out the designs and glue to construction or card stock. If the cards will be given as a gift add envelopes and tie with a ribbon.
Original design.

I remember when I was young, I used to create greeting cards out of those papers and be a little artsy and I would give everybody at home a card. This is good and nice, children can really be sweet and affectionate.
