Cotton seems to be king when it comes to popularity, but is it justified? Listener Rosemary is a linen fan, but wants to know whether eucalyptus bedding lives up to the hype. How do its eco credentials stack up - and what does it feel like? Speaking of feel - silk pillow cases have a reputation for luxury, but listener Cathy wants to know whether sleeping on one will - as the marketing promises - also help your skin and your hair. Could it really help with acne? We'll hear from a dermatologist and a fabrics expert - and there are some surprising answers to this one!If you've seen a claim you'd like investigating, you can email the team on sliced.bread@bbc.co.uk or send us a WhatsApp voice note on 07543 306807.PRESENTER: GREG FOOT PRODUCER: TOM MOSELEY
