This Christmas I’ll be sitting watching the box on tube chair. Just in case a good film comes on, I've made a deluxe model for added comfort. Upcycling an old yoga mat by weaving inbetween the cardboard tubes. This keeps to the theme of being able to build tube chair without any tools, just by using your hands and only making it from existing products; cardboard tubes, cable ties and yoga mat (deluxe version only).
You can even store your new golf balls inside the cardboard tubes.
