This listing is for a vintage fukusa gift cover. See explanation below for how fukusa are used and a bit about their history.

This fukusa is a classic red silk with a large kanji for congratulations (kotobuki in Japanese) done with tiny shibori dots called kaneko (fawn spot). Shibori is a tie-dye technique using hand-sewn resist stitching (in this case) - see video below to learn more.

The backside is the same red silk - with a lightening jacquard pattern - and each corner has a white/gold/red tassle sewn in.

From Wikipedia:
Fukusa are a type of Japanese textile used for gift-wrapping....Fukusa are square or almost square pieces of lined fabric ranging in size from about 9–36 inches (230–910 mm) along one side. They are typically made of fine silk, and may be decorated with embroidery in auspicious designs.

The use of fukusa as a way of presenting gifts has mostly died out, lingering instead mainly in certain ritual exchanges of gifts during weddings in a few regions of Japan.

Traditionally in Japan, gifts were placed in boxes or on a wooden or lacquered tray, over which a fukusa would be draped. The choice of a fukusa appropriate to the occasion was considered an important part of the gift itself, and part of its formality. The practice of covering a gift became widespread during the Edo period (1603-1867).

The scene or motifs depicted on fukusa are chosen to indicate either the occasion for which the gift is being given, or because they are appropriate for one of the annual festivals when gifts are exchanged. The richness of the decoration of the fukusa attests to the giver's wealth and aesthetics.

Once a gift was exchanged, after being admired, the fukusa and box or tray presented with the gift are typically returned to the gift's original giver. However, before the Meiji Restoration, when gifts were presented to a high official, the fukusa was not always returned.
