I've got a door pane and a few small windows I want to cover up but I'm not certain what tools exist. Blinds and curtains require too much time and cost. Are there any easy to use paper-type tool to quickly cover up to block light? It needs to be light too as I have no transportation access.
I have access to a Canadian Tire if that helps.
Edit: Anything a bit aesthetically pleasing that doesn't leave sticky traces?
Edit 2: To save time is there anything such as a self-stick sheets that doesn't leave residue?
