I have made several skeps and I'm in the throws of making some straw globr skeps at the moment but with a difference, I'm making this version which can be taken apart like a modern hive without disturbing the bees as much as the conventional types which are packed full of comb which has to be broken apart ans almost impossible for the inspectors to examine properly.

If anyone would like to have a go I can give you the full details of where to get the traditional long straw used in construction or as you say you can use bramble to make the body.
He is a link to one of the countries best makers, who also supplies kits for making skeps.
