I have been using those plastic feed bags for inner covers, but I'm short on those and have a bunch of nice burlap coffee sacks. I also don't love the way the plastic stuff gets 'stringy' and you end up contributing plastic shreds to the yard. If I could use burlap, any that get too shaggy can go right into the smoker.

Has anyone tried burlap for an inner cover, or would the bees chew it up? Or perhaps there's another reason not to use it.

I've also thought about using canvass, so any thoughts on that could help too...

Thanks,

Adam
