I absolutely love Loaf's Cosy Cotton bed linen. It's exactly as it says, super soft 100% cotton that isn't quite 'brushed' but according to them is tumbled. It's hard to describe unless you've felt it.
Is there anything else like it? Definitely not looking for full brushed cotton. I've tried Bedfolk before which just wasn't that soft and looked at all the usual suspects (Piglet in Bed, Rise and Fall etc) but they all seem obsessed with linen or have cotton that just isn't as cosy.
