Just put three ancient blankets on my local Freegle site, thought they might do for dog's bedding. Now gone a bit nostalgic. Two of them were wedding presents from my late in-laws 48 years ago. Great present though I doubt if youngsters nowadays would appreciate them lol.
I have some cellular ones, I bought from Brentford Nylons (remember - they sold crimplene too ROFL) Had them since 1964. They usually live in a bag in the loft, but have always been brought downstairs if anyone is feeling poorly, or needing to be mollycoddled on the sofa.
I can't bear to throw them out.
