Re: Using a Warre quilt
When I started out with bees (using langstroths), Burlap was commonly used as a mat over the hive and under the lid, in a similar way as described (i think) by Ueli.

Langstroth beekeepers don't want holes in the comb if they can avoid it.
However in a Warré hive, burlap is probably fine directly on the top bars because the beekeeper is not as concerned about comb structure and design, as the method is more about letting the bees do it more or less as they want.
