Hey everybody, Not sure if its ever going to get cold out so maybe it doesn't even matter right now but I'm having an issue with a darkhouse I'm building and I thought I'd ask the community and see if anybody has any ideas. I'm building an Ontario style darkhouse and have most of the parts/materials I need to get started. However I'm at the stage where I need to order the canvas tarp/vinyl tarp and would like to see what others have used. Canvas tarps are tough but are also super expensive especially if I get a custom one made without grommets. Vinyl tarps aren't as tough but I could order quite a few for the cost of one canvas tarp. Does anybody out there have any experience with this? If so what did you do and what would you recommend? This is my first Darkhouse build and my #1 goal is for the house to be pitch black inside. I also want to spend my money wisely
