This construction set from Trigonos is the first one I’ve found come with fabric as one of construction materials. It has wood blocks and sticks as other construction kits. But fabric definitely add unique design elements to the final results. The scales of this construction is a bit big for a small child. It encourage kids to work as a team to build cool structures for fun. All wooden parts and fabric are produced locally at Catalonia, Spain.You can get it directly from its online store.
