Looking good Tacca. What are you putting in it for power?
Yes, covering is harder than it looks, but it's like anything else; once you've got the hang of it, it doesn't seem so hard. It's still not my favourite part of building though.
How often do you plan to remove the canopy? I use small screws to hold on my canopies. You could use small rare earth magnets or Velcro if you need to remove it frequently.
