This is the product offering of an American company (TreasureKnit). You can ask them to knit a plaid, or the surface of a pillow or a blanket starting from the photographic image that you would provide. Even better than the large format prints, here comes tailor-made tapestry.
I doubt it will always produce fine art of the best taste but we can now print our photos on nearly any kind of surface.
Notice: Deliveries are only possible to the United States of Amercia and Canada, for the time being.
