I also found a place in the UK which sells 9cm by 9cm square paper tiles really cheaply - I'd love the official tiles but they are very expensive over here - these tiles are making tangling a lot quicker, before I was working in an 8x8 inch book so each tangle took up a far amount of time.
Looking around at zentangles I keep being drawn to flowers, here is one of my flower tangles on my new paper tiles.
