A beautiful piece of paper, some carefully chosen words, and a couple of folds amount to an origami love letter. No envelope is needed because the paper you write your letter on folds into an envelope. Use the tutorial below to make your own.
I don't know the origin of this very simple design. I used an 8 1/2 x 11" rectangular piece of paper with a scalloped edge. A square also works. I opted to put the text on the patterned side of the paper with a personal note on the inside. No scissors, glue or tape used! Please check out my video; let me know what you think.
