Someone posted a link to find diamond plate fabric a while back and I searched, but couldn't find it. It was black with the diamond plate design.

That was like an automotive diamond plate? Like on a bumper? :D:D:D
This fabric gets sold out as fast as shops get it in LOL I will keep my eyes open for it. The only shop I found so far is back ordered and they don't accept preorders :(

wow i bet that is a great fabric

We have some in our stash. I sent you a PM. :-)

I had a heck of a time finding some grey diamond plate (also called diamond tread) fabric last year when I was making a quilt for my dad. At the time one website was carrying a Kaufman print, I think it was called Easy Riders. I don't remember ever seeing black diamond tread though. Good luck!
