If you're after good quality brushed cotton bedding (flannelette), I highly recommend checking out Dunelm or M&S. Dunelm has some great affordable sets that are surprisingly soft and cozy, especially for winter. M&S is a bit pricier but the quality holds up really well over time.
I’ve also had good luck with John Lewis—their flannelette bedding is super warm and feels luxurious without being too heavy. If you're browsing online, Wayfair and Amazon have loads of options, just be sure to check the reviews first.
Pro tip: you can find all this brand at shaggy rugs ltd
