Hello,

I am looking for some sterling channel wire for ROLLING RINGS. I have
contacted some larger suppliers but without any success ! If any body
can help me, it would be appreciated…

You might try Metalliferous. I use half-round wire to make rolling
rings because channel wire tends to pick up too much gunk, like soap
scum or whatever else the wearers dip their hands into.
