Latest Gardener's World showed a place in Leeds that uses old coffee hessian sacks that have had duffel coat buttons sewn on; basically made a coat for each fern. Very Instagram-friendly.
Somebody on here has posted a link for old coffee sacks on eBay before, they do look nice. I don't think they insulate as well as proper horticultural fleece though, so this year I am going to try a later of fleece first for warmth and then coffee sacks on top for style points
