What landscaping fabric do you all use? I've been looking at Pro 5 as it seems to be most highly recommended on LawnSite, but so far all I've found is on Amazon and is ~$100 for SHIPPING. That's a little more than the price of the roll itself... I wasn't prepared to pay that for shipping. Any other recommendations on professional grade landscaping fabric? I will be using it when I put in river rock for a customer, about 4x30. As I understand it, everything sold at stores like Home Depot are junk and should not be used for a professional, long lasting job.
