They're doing the trick though. Only woke up once last night, and that was due to a hot flush. Pillow was just fine.
And then, today, walking through the shopping centre at lunchtime, what did I find but 1200 thread count sheets. I love my 1000 TC sheets; they're soft and luxurious, so 1200 TC would have to be better again, yes? I'll know soon enough.
