Kakushi Tsutsumi
The Kakushi Tsutsumi wrapping technique is nearly identical to the Otsukai Tsutsumi technique we have shown before, with a slight twist at the end. It resembles an envelope style (Hira Tsutsumi), but it's secured to prevent unintentional unraveling.

How to fold the Kakushi Tsutsumi

Ensure that the item you intend to wrap is at least 1/3 of the diagonal length of the COVER you are using.
The cloth size may also need to be adjusted depending on the height of the item. For very tall items, the fabric should be larger to accommodate this wrapping method.

Spread the fabric in front of you with the side that will be visible later facing downward.
Place the item diagonally in the center of the fabric and fold the bottom corner upward.
Tuck in as needed.

Proceed to fold the upper corner of the fabric over the gift.

Next, bring up the remaining corners of the fabric and tie them together using a granny knot or a square knot .
For rectangular items, a different look is achieved by bringing up the corners of the fabric on each side of the item's longest side first and knotting the edges on the shortest side afterwards.
For square items, the result is the same since all sides have the same length.

Pull out the corner that's hanging over the gift and place it over the knot.

Cover the knot with the remaining fabric to complete the envelope look of your gift.

This way, the item is not only beautifully but securely wrapped, and will not unravel by itself.
