Hira Tsutsumi
In Japan, this wrapping technique is mostly used for envelopes, but it can also be applied to larger objects. The Japanese refer to these cloths as 'Kinpū Fukusa,' but other cultures use them too. In Korea, they are known as 'Yemulbo' and in Turkey as 'Zarf Bohça.'

The Hira Tsutsumi technique is primarily used to wrap envelopes (kinpū) and can also be used for books and other items. If you plan to wrap thicker items, ensure there is sufficient space between the diagonal line and the corners of the COVER.
How to fold the Hira Tsutsumi

Ensure that the item you wish to wrap fits between the diagonal line and the corners of the cover you are using.
The perfect-sized COVER for wrapping an envelope is size XS (35cm x 35cm | 13.8’’ x 13.8’’).

Spread the cloth in front of you with the side of the fabric that should be shown later facing downward.
Arrange the item on the diagonal axis of the fabric, just below the middle line.

Fold the bottom corner upward.
If the corner of the fabric overlaps the item being wrapped, tuck the cloth behind the present to prevent it from slipping out of place.

Continue to fold the left side of the fabric over the gift.

Do the same with the right corner.

Fold the gift over once.

Cover the gift with the remaining fabric to complete the envelope look.
If you'd like to secure it, tie a ribbon around the wrapping.

Voilà!
Your gift is now elegantly wrapped.
