This is the third time I've knitted this pattern in this yarn. At least once I did use another colorway (but only because the LYS didn't have my tomato soup color). These are thick and I have always made them as "house socks". I can't imagine them being worn inside shoes. But the yarn is wonderfully soft and smooshy. Since I've never kept any for myself, I can't attest to how they wear, but they feel wonderful.
They are intended as a Christmas gift to the friend who stitched the lovely Redwork handtowel that is beneath them.
