Purchase attractive stationary that suits your personal style, either printed paper and envelope sets or standard note cards.
Using a pen and scrap paper, practice your handwriting to create a personalized script that embodies the effect you want. Cute writing is typically rounded and may use a circle, a heart, a flower or a star to dot a lowercase "i." Alternatively, if you have messy handwriting, you can emphasize the childlike nature of your scrawl.
Write a salutation on the top of your letter paper or inside a note card. This can be the name of the person the letter is for or the standard "Dear" used in most communications.
Write the main text of your letter. Emphasize the positive. Pay attention to your spelling and maintain consistent handwriting.
Sign off your letter with a friendly closure such as "Love and kisses" or "XOXO" and your signature. Your signature may be embellished with doodles or decorative flourishes.
Decorate your letter with stickers or hand-drawn illustrations. Be sure to leave the text legible.
Address your envelope. Use either the name of the recipient or the mailing address, depending on if you are giving this letter in person or sending it through the post. In the latter case, include your return address in the top left corner.
Fold the letter or close the note card and insert into the envelope. Seal the envelope with a pretty sticker.
