I had this idea from an old Italian fairy tale...where a frog made of her husband a king!
"One king had three sons and decided to make his successor the one of them that had a wife that was better at weaving. So one evening the three brides were invited to the royal palace to show which one made the more beautiful weaved canvas. The first son arrived with a gorgeous wife, that made a really gorgeous canvas, the second son arrived with a even more beautiful wife, that had waved a canvas of incredible finish and color. Then arrived the third son... with a frog! The frog only brought a walnut... but when the queen opened up the walnut it come out from it the finest and more precious silk canvas, weaved with the most beautiful color and virtuosity! (off course eventually the frog convert in a beautiful princess!).
When I were little and my parent narrated me this story I always wanted to have one of these walnut!
Step 1: WHAT YOU NEED
-thin paper sheet;
-red nail polish;
Step 2: OPEN AND EMPTY THE WALNUT
If it doesn't open exactly in the middle is fine anyways, the important is to don't break off any pieces of the shell.
Step 3: CUT THE PAPER
You can cut a long thin stripe, or a square shape.
You won't tell it but in a walnut it fit more paper than you tink!
Step 5: FOLD THE PAPER
Step 6: PLACE THE LETTER IN THE WALNUT
If your walnut is big enough you can also put in it a small jewellery piece or a small present.
