Cardstacking a 20 foot Card Tower

All cards are freestanding - no tape, glue, bending or folding. This project was built to launch my new YouTube channel - cardstackers - which will be dedicated solely to new cardstacking projects. With almost 4000 decks, I have plans for many big projects over the next few months. I have a book full of sketches and plans for at least 30 projects. Please subscribe if you would like to be notified of new videos as they are posted. I spent about 40 hours on this tower and it used about 29,000 cards.
