Furoshiki gift wrapping
Furoshiki is the name of the squared fabric used to wrap and carry all types of objects, clothes, gifts, or even bottles.
This technique is an art in Japan and 100% ecologic, because the fabric can still be used for other packaging, taking care of the environment and forgetting the polluting plastic bags.
It is not essential to use japanese furoshiki cloth (available at Furoshiki or Furochic), but anyone who has a nice texture or pattern can be useful (Ikea always has a good selection or the well-known Finnish company Marimekko, with its colorful and distinctive patterns and fabrics.)
