A shirt and tie is a traditional gift for Dad -- a card to match is something new.
Martha Stewart Living, June 2004
Place paper facedown. Fold in half vertically; unfold. Line up left edge with centerline fold, and crease; repeat with right edge. Unfold, and lay flat.
Fold top-left corner in to line up with outermost crease, forming a triangle; repeat on top-right corner. Using index fingers and thumbs, pinch together outside points of each triangle so they meet, and crease.
While still pinching triangles, fold down top edge (this will make sleeves).
Turn paper upside down, and flip it over. Fold down top edge 3/4 inch.
Flip paper over. Fold top left and right corners so tips meet at centerline.
Tuck bottom edge under collar, and flatten by creasing. For the tie, cut out an 8-by-1/2-inch strip of decorative paper. Knot paper. Snip close to knot on one side; trim other to a point. Glue to shirt.
