That's good to know. We're happy with the Garnet Hill sheets so far. We have a flannel duvet cover from them (also Portuguese flannel) which has lasted probably 8 years without much wear (we use it seasonally). Their flannel though is very thick- one of the fitted sheets I bought is 3 times the thickness of the flannel sheets I paired one of them with and makes the old sheets feel scratchy and cheap, to be honest. (The old thin flannel sheets were a target $13 special, pretty sure made in China.) So perhaps the recommendation is Portuguese flannel from Garnet Hill.
