Since you wrote, "I would like to do a single width with a traditional selvedge end.", I assume you are not interested in Lochcarron cloth because of their tuck-in selvedge?

Does HoE do traditional selvedge? If so, are they the only weaver other than Dalgliesh? If "yes" to both, then xman has pretty much hit the nail on the head. You have a decision to make.

Good luck, whichever path you take. I prefer heavy weight, because it hangs better. Some folks find lighter/medium weight cloth cooler.
