HGTV recently featured on Landscaper's Challenge - precut flagstone that was machined and joined by a strong poly-type mesh or web. It fit together like a puzzle piece and could be trimmed to be free forming. I found an out of state dealer while searching the HGTV website, but would really like to find a carrier in the Nashville, TN area. One other person mentioned in Connecticut it was found in Home Depot, not so here. This material was not found at Home Depot or Lowe's. Any ideas? Thanks for any help you can give!

Ask the dealer who is his manufacturer. Contact the manufacturer and ask for local dealers/suppliers.

I am on a search for the same thing and I think I've found it. Check out:

Best of luck!

Here are a couple of other sites you can try:

Peninsularoxpro .com

Sepulveda .com - click on smokestack flag mat, then product info - will give different colors, etc.

I am contacting my local stone supplier to see if they carry this. It looks like it is known as "flag mats" in the masonry industry.
