A calligraphed monogram from your wedding ceremony or a clip-art letter can be scanned into your computer and used as either a graceful embellishment or a bold graphic detail. A single repeated letter or a pair of initials makes a splashy customized cover for a note card.
With a desktop-publishing program, copy and paste initial to fill an 8 1/2-by-11-inch page on screen. Print onto card stock; cut out a 5 1/2-by-8-inch rectangle, partly cutting off some letters. Fold in half.
You can fit two cards on an 8 1/2-by-11-inch sheet; for each, position first initial on the right edge and second initial on the left. Print onto card stock, and cut cards apart. Fold sides of each to meet at center.
On a computer, copy and paste initial to fill page. Print onto colored paper; cut 1/8 inch smaller than the dimensions of the envelope with flap open. Slip the paper inside the envelope; fold the top corners using the angled edge of flap as a guide, leaving a 1/2-inch border. Remove and trim; attach with glue stick.
