There are no manufacturing facilities in North America at this time that are able to produce hemp woven products, such as webbing, fabrics, twine, rope, yarn.
It's a very costly investment for a manufacturer/processor to set up and operate for this type of venture. There aren't enough American hemp farmers producing long fiber varieties of industrial hemp, but it WILL happen in the coming future if it's proven to be healthier, wealthier and more sustainable economically and environmentally!
