Ray,

it's used as a weed block (we put it down in flower beds and cover with mulch). Got it at a nursery; can't remember the brand name. It's not the black plastic mesh stuff (which would be useless for this application); this has texture similar to Tyvek (maybe a bit stiffer), comes in a dark brownish color, cuts easily, doesn't seem to fray. I believe this is what they call spunbond. I actually saw some at Costco the other day; a big roll for about $25.

Regards,
Scott
