Where can you get the clear 1/4" mesh for aquarium top?

I have tried Home depot, Rona, Co-op and Canadian tire and have never found the clear mesh. All they had was the green or black variety.

Bulk Reef Supply now carries the 1/2" and 1/4" clear mesh in 6.5' x 2.5' pre-cut pieces. Sadly they've been sold out for quite some time now as I've been wanting to build a mesh lid as well.
