Sourcing Camera Strap webbing/parts?

So I am looking for a source to buy camera strap webbing (the thin kind that is apox. 1cm wide) I want to make a few camera straps (i will sew this thiner stuff int a wider webbing with an industrial sewing machine)

I am also looking for the plastic bits that allow you to loop the strap through the camera and back onto the strap. See the reference pic below. In general I am looking for where to buy the parts of the strap "below" the rings.

Fabric stores may have some of what you seek.

Eastern Mountain Sports, REI, sporting good stores sell webbing by the foot in many colors n widths as well as cam buckles n spade buckle misc hardware. This stuff is common DIY supplies for mt climbers n campers.

Hi,
I purchased some webbing from strapworks.com. They are boating people that are into rigging stuff. They have (as Tractor Supply says), "the stuff you need out here".
