Hi, just wondering if bunnings offer in store workshops as I'd love to learn how to build a cat tunnel that runs along my entire fence around my yard. i don't want the tunnel to run on the ground but on the fence. I've never used a drill or anything at all, in fact I only own a hammer. I have some pics of what i'd love to attempt to build but I'm worries I'll stuff it up and the money i will of spent on materials will be wasted and I don't have a lot of money to be throwing in the bin. TIA
