Explanation:
Lay a square napkin down on a clean work surface so that it's open all the way. Iron if needed.
STEP 2: FOLD IN DIAGONAL HALF
Grab a hold of the right hand corner nearest you and fold it over to meet the opposite upper left corner. Straighten out the edges so that they all meet up.
STEP 3: TURN IT
Turn the triangle so that the longest side is parallel to you and the table's edge.
STEP 4: FOLD IN
Fold the left corner in so that it sits JUST past the midway point of the long side of the triangle, like pictured.
STEP 5: FOLD IN AGAIN
Now repeat for the right hand corner.
STEP 6: FOLD OVER
Take the lower left corner and bring it in to the bottom midpoint of the now 'house' shaped napkin. Press the new left side fold down.
STEP 7: FOLD OVER AGAIN
Repeat on the right side.
STEP 8: FOLD UP
Take both bottom corners and bring them up to rest just below the top right corners. Press down the new folds.
STEP 9: CLOSE THE ENVELOPE
Take the top point of the envelope 'flap' and bring it down (or close it) to complete the envelope.
STEP 10: ADD A PERSONALIZED CARD
Use your envelope napkins to include a personalized 'letter' or card to each guest's plate. Some ideas for what this could be are:
holiday greeting card
menu
place card
family photos from past celebrations
holiday story or poem
coloring cards with pencil crayons for kids
game cards: trivia, scavenger hunt, etc
